摘要
作者采用高频红外吸收法同时测定Ag中的C和S,对试样的制备、助熔剂的选择、分析条件等进行了较详细的研究。方法快速、简便、灵敏度高,C、S的测定范围分别为0.002%～1%和0.002%～0.1%,对自己配制的合成样进行6次平行测定,其RSD分别为:C=0.34%和S=2.01%,C、S的回收率都在95%～105%,获得了满意的结果。
A method for determination of trace carbon and sulfur in pure silver is proposed. Conditions for the analysis are optimized. The ranges of analysis are 0.002%- 1% for carbon and 0.002%-0.1% for sulfur, the RSD（n=6） are 0.34164% -2.01231%, the proposed method is simple and fast.
