摘要
用有机溶剂法制备硫酸四氨合铜,再用返滴定法对NH3含量进行测定,阐述了该方法的测定原理;制备的[Cu(NH3)4]SO4晶体中,NH3含量为27.90%,其结果与理论值基本吻合。与传统方法相比,新方法测定误差略高,但测量速度提高。
Cuprammonium sulfate was prepared by an organic solvent method, in which NH3 content was determined by titration method on the measurement principle which was explained in the paper; Preparation of [ Cu （NH3 ） 4] SO4 crystals, NH3 content of 27.90%, and its results consistent with the theoretical value. Compared with traditional methods the new one had a zlightly measurement error, and a higher speed.
