摘要
用氯离子选择性电极对双甘膦中的氯离子含量进行了定量测定。测定结果表明：氯离子浓度的对数与测得电位值在0．0005--0．1g／L之间线性相关，其相关系数为0．9985。对实际样品进行了回收率测定，其回收率为97．22％--103．26％之间。结果表明该方法测定迅速、准确、简便、经济且高效，有较高的灵敏度和重现性，适用于工业大生产中的中间体和产品测定。
The concentration of chloride ion in PMIDA was determined by chloride anion selective electrode. the linear range is from 0. 0005 to 0. 1 g/L. And the linear correlation coefficient Rz is 0. 9985. The Recov- ery was detected between 97. 22~103. 26 %. The results show that the method is simply, easy, economi- cal and efficient, it can be used for the determination of intermediate product and product in industrial pro- duction.
