摘要：

The use of ethylenediamine in the voltammetric study of copper in natural sea water was evaluated for applicability with rotating thin mercury film electrodes. It was shown that this method increases the analytical sensitivity for copper at such electrodes by at least a factor of 4, and improves the detection of pH 8 labile copper.
