伏安极谱法同时测定海水中的铜、镉、铅、锌

Voltammetry Method is Used to Determine Copper, Cadmium, Lead and Zinc in Seawater

建立伏安极谱法同时测定海水中铜、镉、铅、锌的方法。方法：海水于-1．15V恒压电解，通过标准加入法对海水中铜、镉、铅、锌进行定量。结果：方法检出限为0．06—0．99μg／L，定量限为0．50—10．00μg／L，回收率为80．40—105．8％。方法具有灵敏度高、抗干扰性能强、操作简便等特点，并且满足海水中铜、镉、铅、锌的监测分析要求。

A method for determination of copper, cadmium, lead and zinc in seawater was established. Methods： the seawater was electrolyzed by -1.15V constant pressure, and the copper, cadmium, lead and zinc in seawater were quantified by standard addition method. Results： the detection limit of the method was 0.06-0.99, g/L, and the quantitative limit was 0.50-10.00, and the recovery rate was 80.40-105.8%. The method has the characteristics of high sensitivity, strong anti-interference performance and simple operation, and meets the requirements of monitoring and analysis of copper, cadmium, lead and zinc in seawater,
