在电化学分析及电极过程动力学研究中,表面活性物质在电极上的吸附,常使测量结果受到严重影响。在天然水的反向极谱分析中,由于天然水,特别是海水,含有大量表面活性物质及悬浮体,并且分析溶液又进行搅拌,因此对电极的灵敏度及重演性影响特别严重。用汞膜电极测定一个新采集的海水样品后,即需重新涂汞。与国际海 In electrochemical analysis and electrode kinetic studies, the adsorption of surface-active substances on the electrode often causes the measurement results to be seriously affected. In the reverse polarographic analysis of natural water, the sensitivity and repeatability of the electrode are especially affected by natural water, especially seawater, which contains a large amount of surface-active substances and suspensions, and the analysis solution is agitated. Mercury film electrode measured a newly collected samples of sea water, the need to re-coated mercury. With international sea
