Ms. Grilikhes et al., STRIPPING VOLTAMMETRIC ANALYSIS OF ZINC, CADMIUM, LEAD, AND COPPER IONS IN CHLORIDE SOLUTIONS, Russian journal of applied chemistry, 70(7), 1997, pp. 1063-1066
A stripping voltammetric procedure with a solid indicator electrode is
developed for determination of zinc, cadmium, lead, and copper ions,
present simultaneously in the chloride supporting solution at a level
from the maximum permissible concentration (MPC) to 100-500 mu g l(-1)
, providing the relative error from 25-30 (the lower concentration lim
it) to 10% (the upper limit).
