二氯荧光黄为指示剂的硝酸银滴定法测定废水中氯化物

摘要

采用以二氯荧光黄为指示剂的硝酸银滴定法测定废水中氯化物.优化实验条件后,以该法测定质控样,相对误差-1.30％～2.70％,相对标准偏差0.19％～0.14％,加标回收率约为98％.用该法测定废水中氯化物是合理可行的.%The article described the determination of Chloride in waste water by Silver Nitrate titration with dichlorofluorescein asrnindicator. The QC sample was determined after optimizing experimental conditions. Results showed that the relative deviation rangernfrom - 1. 30% to 2. 70% , RSD range from 0. 10% to 0. 14% .recovery was. ahout 98% . This method is not only reasonable butrnalso feasible for determining Chloride in waste water.
