Elimination of the copper-zinc interference in anodic stripping voltammetry by addition of a complexing agent.

Abstract

The addition of cyanide and Triton X-100 suppress the formation of the CuZn intermetallic compound in ASV making it possible to determine traces of zinc(II) in the presence of an excess of copper ions. The precision of the method (5%) and the accuracy (error of 1.4%) in sea water are satisfactory.
