AB  - Due to the similar chemical properties of Ni2+ and Co2+, several dozens of adsorptive stripping voltammetric (AdSV)
methods have been developed for their simultaneous determination. The question was would there be some benefits
if a stripping method made for simultaneous determination of Ni2+ and Co2+ will be optimized for the determination
of only one of them (Ni2+). It was found that the optimized method has for an order of magnitude lower LOQ (1.89 ×
10-10 M), an order of magnitude lower influence of Co2+, and the applicability of one calibration line for four orders
of magnitude of Ni2+ concentration. The influence of some common anions and cations has been examined. The
developed method was successfully applied for nickel content determination in real samples. The suitability of the
developed method for the determination of Co2+ from the same solution in the second run, upon optimizations of
deposition potential and time, was also explored. The LOQ obtained for Co2+ (3.61 × 10-11 M) is almost two orders
of magnitude lower than LOQ of the method for simultaneous determination of both cations and, its LOD and LOQ
are among few lowest obtained by AdSV methods for Co2+ determination. The developed method for Ni2+ and Co2+
determination from the same solution in two successive runs has significantly better analytical performances than
the starting method for their simultaneous determination in one run.

from this work and the model of Pitzer’s were used to determine the mixing parameters. Good agreement
was found between the experimental and calculated values of the mean ionic activity coefficients of NaCl
with a standard deviation of fit 1.5 × 10–3. The values of the osmotic coefficients of the system {yNaCl +

AB  - The mean activity coefficients of KCl in the ternary system {y KCl + (1 – y) K2HPO4}(aq) were experimentally determined at T = (298.15 ± 0.01) K by the electromotive force measurement (EMF method) using the cell of the type, K–ISE∣KCl(mKCl), K2HPO4(mK2HPO4)∣Ag∣AgCl (ISE = ion-selective electrode), in the range of total ionic strength of the solution Im = (0.10 to 1.00) mol·kg−1 at different ionic strength fractions of KCl being y = (0.1011; 0.1997; 0.3016; 0.4027; 0.5006; 0.6018; 0.7018; 0.8051; 0.8988; 1). In addition, the osmotic coefficients of the system have been measured at the same temperature by the isopiestic vapor pressure method over the range of ionic strengths from (0.96698 to 2.21602) mol⋅kg−1 using KCl(aq) as the reference solution, at ionic strength fractions of KCl being y = (0.2063; 0.3849; 0.6099; 0.8011; 1). Values of the mean ionic activity coefficients of KCl and osmotic coefficients in the system {yKCl+(1–y)K2HPO4}(aq) were treated by an extended form of Pitzer's ion-interaction model, Scatchard's neutral-electrolyte model and Clegg–Pitzer–Brimblecombe's equations based on the mole-fraction-composition scale. All three models gave similar quality representations of both sets of experimental results. There are two sets of previously published isopiestic data that were taken into consideration during treatment. The model parameters were fitted and optimized to all available thermodynamic data from EMF and isopiestic measurements to obtain an accurate and self-consistent description of properties and to form a set of parameters that can be used in a wide range of ionic strength of the system. The standard deviation of the fit for the ionic strength range from Im = (0.0897 to 10.4350) mol·kg−1 with two optimized mixing parameters of Pitzer's model without higher–order electrostatic terms was for the mean ionic activity coefficients of KCl and osmotic coefficients, s.d. (γ±) = 3.5⋅10–3 and s.d. (ϕ) = 4.7⋅10–3 respectively, with two optimized mixing parameters of the Scatchard model standard deviations were s.d. (γ±) = 4.9⋅10–3 and s.d. (ϕ) = 5.0⋅10–3 and with Clegg–Pitzer–Brimblecombe's model higher–order electrostatic terms not included, standard deviations were s.d. (γ±) = 4.2⋅10–3 and s.d. (ϕ) = 4.8⋅10–3.

AB  - This study was focused on in vitro screening of the total antioxidant activity of the selected extracts of the mushroom Coprinus comatus and quinic acid, one of their antidiabetic ingredients, by an uncommon electrochemical assay. Indeed, direct current (DC) polarographic HydroxoPerhydroxo Mercury(II) Complex (HPMC) assay based on decrease of anodic limiting current originating from HPMC formation in alkaline solutions of hydrogen peroxide at potential of mercury dissolution, observed upon gradual addition of antioxidants, was applied herein for the estimation of the natural products' antioxidativity. Quinic acid was found to exhibit most promising antioxidant potential (4.0 +/- 0.2%mu L-1) being approximate to 2-fold more active than the screened C. comatus extract samples. Actually, such a finding puts some light on the antioxidativity of cyclic polyols, well understimated class of organic compounds, compared to aromatic (poly)phenolics. As a low cost, easy-to handle and accurate this polarographic assay may be thoroughly recommended for much broader use.

The 33 osmotic coefficients for the ternary mixtures were likewise represented with these models, using both the usual Pitzer mixing terms and also Scatchard's neutral-electrolyte model mixing terms for the extended ion-interaction model. Two mixing parameters are needed for each of the three models for {yK(2)HPO(4) + (1 - y)KH2PO4}(aq), and both of these ion-interaction models give similar high-quality representations of the experimental results. However, the Clegg, Pitzer and Brimblecombe model had more difficulty in representing the osmotic coefficients of K2HPO4(aq), especially below 3 mol.kg(-1), and consequently the corresponding mixture model with two mixing parameters is slightly less accurate for representing the osmotic coefficients. The maximum difference in calculated values of the mean molality-based activity coefficients for the two recommended extended Pitzer models with the different types of mixing terms are 0.0061 for the trace activity coefficient of K2HPO4(aq) in KH2PO4(aq) but with much better agreement at most mixture compositions.

It also showed a good AO activity in the polarographic HPMC assay (950%/mL). p-Hydroxybenzoic acid may be one of the responsible compounds for the afore-mentioned activities. The same extract also exhibited a concentration-dependent cytotoxicity against MCF-7 and HepG2 tumour cell lines reaching IC50 values of 123.51 and 134.29g/mL, respectively with no cytotoxic activity against normal MRC-5 cells. Gentisic, syringic and protocatechuic acids may be among the bioactive principles for the observed cytotoxicity.

AB  - The possibility of reduction of vanadate monomer in the mycelium of fungus Phycomyces blakesleeanus was investigated in this study by means of polarography. Control experiments were performed with vanadyl [V(IV)] and vanadate [V(V)] in 10 mM Hepes, pH 7.2. Addition of P. blakesleeanus mycelium resulted in disappearance of all V(IV) polarographic waves recorded in the control. This points to the uptake of all available V(IV) by the mycelium, up to 185 A mu mol/g(FW), and suggests P. blakesleeanus as a potential agent in V(IV) bioremediation. Polarographic measurements of mycelium with low concentrations (0.1-1 mM) of V(V), that only allows the presence of monomer, showed that fungal mycelia removes around 27% of V(V) from the extracellular solution. Uptake was saturated at 104 +/- 2 A mu mol/g(FW) which indicates excellent bioaccumulation capability of P. blakesleeanus. EPR, V-51 NMR and polarographic experiments showed no indications of any measurable extracellular complexation of V(V) monomer with fungal exudates, reduction by the mycelium or adsorption to the cell wall. Therefore, in contrast to vanadium oligomers, vanadate monomer interactions with the mycelium are restricted to its transport into the fungal cell, probably by a phosphate transporter.

abstract = "The possibility of reduction of vanadate monomer in the mycelium of fungus Phycomyces blakesleeanus was investigated in this study by means of polarography. Control experiments were performed with vanadyl [V(IV)] and vanadate [V(V)] in 10 mM Hepes, pH 7.2. Addition of P. blakesleeanus mycelium resulted in disappearance of all V(IV) polarographic waves recorded in the control. This points to the uptake of all available V(IV) by the mycelium, up to 185 A mu mol/g(FW), and suggests P. blakesleeanus as a potential agent in V(IV) bioremediation. Polarographic measurements of mycelium with low concentrations (0.1-1 mM) of V(V), that only allows the presence of monomer, showed that fungal mycelia removes around 27% of V(V) from the extracellular solution. Uptake was saturated at 104 +/- 2 A mu mol/g(FW) which indicates excellent bioaccumulation capability of P. blakesleeanus. EPR, V-51 NMR and polarographic experiments showed no indications of any measurable extracellular complexation of V(V) monomer with fungal exudates, reduction by the mycelium or adsorption to the cell wall. Therefore, in contrast to vanadium oligomers, vanadate monomer interactions with the mycelium are restricted to its transport into the fungal cell, probably by a phosphate transporter.",

AB  - Antioxidant (AO) activity of extracts of hop cones (Serbian domestic varieties) and commercial hop products (Saaz, Spalter, Spalter select, and Magnum pellets) was determined by parallel application of recently developed direct current (DC) polarographic and widely used DPPH assay. Correlations between 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) scavenging and total phenolics (TPC) determined by the Folin-Ciocalteu assay (FC) (0.99), and between H2O2 scavenging,: (HPS) and humulone content (H) determined by conductometric method (0.94), total resins (TR) (0.85), and hop storage index (HIS) (-0.90), were found statistically significant at p  lt  0.05 level while complete lack of HPS correlation with TPC and DPPH was observed. To obtain an insight into differences between results of AO assays applied, activity of individual compounds, prevalent hop phenolics, and bitter acids was determined. By far superior HPS activity of humulone was followed by catechin, quercetin, xanthohumol, lupulone, and rutin. In contrast, DPPH scavenging activity of phenolics (quercetin > catechin > rutin > xantohumol) was found substantially higher than activity of bitter acids. According to ferric reducing antioxidant power (FRAP) and scavenging of 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), higher AO activity was ascribed to phenolics, while almost neglecting humulone. Besides reliability, low cost, and an easy-to-handle procedure, an ability to recognize humulone as the major contributor of hop AO activity could allow DC polarographic assay to be applied in analysis of various hop-derived products.

AB  - The behavior of chlorogenic acid (CGA) and its interaction with Hg(II), Pb(II), Cu(II), Cd(II) and Zn(II) has been studied using direct current (DC) and differential-pulse polarography (DPP). Adsorptive and kinetic/catalytic anodic waves of CGA have been detected at -0.02 and -0.18 V vs. SCE, respectively; Hg(I)-CGA surface disproportionation has been assumed. Reduction of Hg(II)-ions, added in the buffered solution of CGA (pH 7.5), occurs rather than complexation, while the complex forming ability of CGA towards Pb(II) and Cu(II) has been observed. Stoichiometry 1?:?1 for Pb(II)-CGA, and 1?:?1 and 1?:?2 for Cu(II)-CGA has been established applying Jobs method of continuous variation on DPP data. UV-vis spectrophotometric measurements additionally confirmed the existence and stoichiometry of Cu(II) complexes.
