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.
