摘　　要：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。A new oxygen flask method was used in simultaneous microdetermination of S and Cl in chelate resin for selecting optimum reaction conditions of synthesis of chelate resin such as solvent, reaction temperature, reaction time ect. . The satisfactory results were obtained. This method was compared with the conventional oxygen flask method which determine S and Cl for chelate resin respectively. S and Cl in seven types of samples were determinated, the relative error in five samples was less than 3% , and the standard deviation was 0.11%. It showed that this analytical method is simple, convenient and rapid.
