Copper (II) was selectively accumulated on a hanging mercury-drop electrode by using 2-
mercaptobenzimidazole. Ensuing measurements were carried out by differential pulse
adsorption stripping voltammetry. Factors affecting the accumulation, reduction, and
stripping steps were investigated and a procedure was developed. The optimum conditions
for the analysis of copper were pH 5.0, 5.33× 10-5 M 2-mercaptobenzimidazole and an
accumulation potential of-0.10 V (vs. Ag/AgCl). A linear range was obtained in the ...
