肥皂中氯化物含量的测定 应用资料在测试样品中加入甲醇后,用0.1ml/L硝酸银溶液滴定法测定肥皂中的氯化物(转化为氯化钠)。终点由滴定曲线上的拐点决定。氯离子浓度由硝酸银的滴定体积计算得出。TIE-92004enL上海市徐汇区宜山路333号1201室网址: http://www.kem-china.comIKYOTO ELECTRONICSMANUFACTURING CO.,LTD. Application MemoChloride in Soap Industry Cosmetics soapInstrument Automatic potentiometric titratorMeasurement method Precipitation titrationStandards ISO 457, QB/T 2623.6 1.Overview The chloride (converted to NaCl) in soap is measured by titration with the 0.1ml/L silvernitrate solution after methanol is added to the test sample. The endpoint is determined by theinflexion point on the titration curve. Chloride concentration is calculated from the titrationvolume of silver nitrate. 2.
