Abstract
Amperometric determination of Zn(II), Cd(II) and Hg(II) was carried out with the help of ethanethioic acid (ETA) at d.m.e. in 0.1 M K2SO4, 0.1 M NH3 + 1.0 M NH4Cl and 0.1 M HClO4 medium respectively. Metal ions solutions were used as titrant (anodic titrations) in all the cases. Metal species-ETA stoichiometry was 1 : 2 for each metal. Solutions as dilute as 6.54 ppm (Zn), 11.24 ppm (Cd) and 10.03 ppm (Hg) were estimated with high degree of accuracy. Tolerance limit for foreign ions has also been worked out.
