采用氧瓶法同时测定螯合树脂中微量硫和氯,用于确定螯合树脂合成的最佳反应溶剂、温度、时间等条件,取得满意结果。此法对用常规氧瓶法分别测定树脂中的硫和氯进行比较,七种树脂样品氯元素测定,五种样品的相对误差小于3％;标准偏差为0.11％,是一种优化螯合树脂合成条件的简便、快速的分析方法。
Simultaneous determination of trace amounts of sulfur and chlorine in the chelating resin by the oxygen bottle method was used to determine the optimal reaction solvent, temperature and time for the synthesis of the chelating resin and satisfactory results were obtained. This method for the determination of sulfur and chlorine in the resin by the conventional oxygen bottle method, the determination of chlorine content of the seven resin samples, the relative error of the five samples is less than 3%, the standard deviation of 0.11%, is an optimized chelating resin Synthetic conditions of the simple, rapid analysis.
