摘要
作者采用硫氰酸汞比色法测定纯碱中氯化钠的含量.精确度比较好,并且比GB2369-80规定的容量法快速、简便、结果重复性好、试剂容易得到,也易于推广.
The content of NaCl in soda ash is determined by colourimetry of mercury thiocyanate. The accuracy by this method is pretty good and more simple and faster than volumetric analysis method required by GB 2369-80, the result repeats better, furthermore, it is easy to obtain the reagent and to be popularized.
