乳化剂OP作稳定剂以比浊法测定水中氯化物的含量

TURBIDIMETRIC DETERMINATION OF CHLORIDE USINGPOLYETHYLENEGLYCOL OCTYLPHENYLESTHER

提出了用聚乙二醇辛基苯基醚（ＯＰ）比浊法测定水体中氯含量的新方法．吸光度和氯的浓度在２０～２４０μｇ／２５ｍｌ范围内呈良好的线性关系．该方法用于测定自来水和鱼塘水中氯含量，相对标准偏差小于５％，用于５种不同氯含量的水样分析，回收率为９５．２％～１０８％．

The turbidimetric determination of chloride in water using plyethyleneglycol octylphenylestherwas developed. There is good liner relationship. between absorbance and concentration of chloride onthe rarise of 20～240 μg/ml. The relative standard deviation of determination is less than 5% for thedetermination of tape water and fish pond water. The procedure has been applied to determine the chlo-ride in several water samples, the recovery is 95%～108%.
