本文研究了汞离子选择性电极的制备、性能测试及其在含汞污水中的应用。采用间接法和直接法测汞,经实际应用表明,间接法获得满意的结果,电极性能良好,测定下限可达10~(-7)M Hg~(++),测Hg~(++)时,污水不必予先处理,达到快速、准确、灵敏和操作简便的要求。 This paper studies the preparation of mercury ion selective electrode, performance testing and its application in mercury-containing wastewater. The indirect method and the direct method were used to measure the mercury. The practical application showed that the satisfactory results were obtained by the indirect method, the electrode performance was good, the lower limit of determination was 10 ~ (-7) M Hg ~ (++) When the sewage does not have to be treated first, to achieve fast, accurate, sensitive and easy to operate requirements.
