摘要：

The addition of cyanide and Triton X-100 suppress the formation of the Cu-Zn 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.
