研究了二乙氨基二硫代甲酸钠测水样中铜的光导光度分析方法。５个天然水样中的铜测量结果与用原子吸收法测量的结果基本一致，５个水样测量的平均相对误差为５７％，测量灵敏度比用１ｃｍ比色皿测量提高约１１２倍。
The photometric detection of copper in aqueous samples by sodium diethyldithiocarbamate was studied. The results of copper measurement in 5 natural water samples were basically the same as those obtained by atomic absorption spectrometry. The average relative error of 5 water samples was 57%, and the measurement sensitivity was about 112 times higher than that of 1cm cuvettes.
