CS_2的分析,多采用二乙胺——醋酸铜比色法。该法呈色后,经一定时间放置,铜液易析出。为了稳定溶液中的铜盐,有以该法为基础同时加入一定量三乙醇胺的比色法。为了寻求更有效的方法,我们参考了有关资料,对以该法为基础,用硫酸铜代替CS_2配制标准液,用盐酸二乙胺代替二乙胺的二乙胺硫代甲酸钠——铜盐法进行初步探讨。结果如下: CS_2 analysis, more use of diethylamine - copper acetate colorimetric method. After the method of coloring, after a certain period of time, easy to precipitate copper. In order to stabilize the copper salt in solution, there is a colorimetric method that adds a certain amount of triethanolamine on the basis of this method. In order to find a more effective method, we refer to the relevant information on the basis of the law, with copper sulfate instead of CS_2 standard solution, with diethylamine hydrochloride instead of diethylamine - sodium salt of copper - For a preliminary discussion. The result is as follows:
