Direct Electrolysis-atomic Absorption Spectrometric Method for Determination of Total Copper in Antifouling Paints

The direct electrolysis- atomic absorption spectrometric method was used to determine the copper content in antifouling paints,and after electrolysis the atomic absorption spectrometry was used to determine the residual copper content in solution,and then sum the Cu content of both methods as the total Cu contents in antifouling coating,thus improve the accuracy of detection of total copper content.
