本文提出用硫代米氏酮(TMK)双波长分光光度法同时测定金和银的新方法。该法选择性。灵敏度及稳定性均较好,对Au(111)和Ag(1)的表观摩尔吸光系数分别为,同时在0—60.0μgAu/25ml和0—8.1μgAg/25ml范围内符合比耳定律。
This paper presents a new method for the simultaneous determination of gold and silver by the dual wavelength spectrophotometry of thiomyl ketone (TMK). The law is selective. The sensitivity and stability of Au (111) and Ag (1) were comparable to Beer ’s law in the range of 0-60.0μgAu / 25ml and 0-8.1μgAg / 25ml, respectively.
