基于汞修饰玻碳电极，采用阳极溶出伏安法对水中铅和镉同时进行测定。实验结果表明：采用同位镀汞的阳极溶出伏安法同时检测铅和镉可得到灵敏的溶出峰，溶出峰衰减慢，电极维护周期间隔长，当沉积时间为150s时，测量相对标准偏差分别为1.13%和1.40%，检出限分别为0.38μg/L和0.31μg/L，测定地表水及污染源废水铅和镉的回收率均接近100%，可用于地表水及污染源废水中铅和镉同时在线检测。

The paper indicates; By adopting anode to dissolve out voltammetry, lead and cadmium are determined and the sensitive dissolving peak can be received. The dissolution peak attenuates slowly and the long interval maintenance period of electrode is kept. When sediment time is at 150s, the precision degree of lead and cadmium is 1.13%and 1.40%separately, the determining limit is 0.38μg/L and 0.31μg/L separately. The recovery rates of lead and cadmium from surface water and waste water of pol uted sources are at 103.2%~109.6%and 98.3%~101.3%, lead and cadmium from surface water and waste water of poluted sources are determined on line.
