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.
