半微分电分析法是最近几年发展起来的一种新的电分析技术。在国内尚未见文献报道,在国外1975年第一次应用于悬汞电极,1979年Goto等人应用于镀汞薄膜电极,但未见有实际应用的报道,更未见有“半微分电分析器”出售。我们于去年在中山大学开始对半微分电分析法进行了研究,自制半微分电分析器,把半微分电分析法运用到阳极溶出伏安法中,并用镀汞薄膜电极、玻碳电极和汞膜电极对海水和 Semi-differential analysis is a new type of electrical analysis developed in recent years. In the literature, it has not been reported in our country. It was first applied to hanging mercury electrode in 1975 in 1975, Goto et al. Were applied to mercury thin film electrode in 1979, but no practical application was reported. Device "for sale. Last year, we started researching the semi-differential analysis method at Sun Yat-sen University. We made a semi-differential electroanalyzer using the semi-differential analysis method in the anodic stripping voltammetry. We also used the mercury-plated thin film electrode, glassy carbon electrode and mercury Membrane electrode to sea water and
