摘要
应用离子色谱法检测了乳化液中的氯离子。采用萃取分离法 ,消除乳化液中有机组分对测定组分的影响及对色谱柱所造成的污染。方法具有良好的精度 ,加标平均回收率为 95 %～ 10 5 % ,相对标准偏差优于 4 .0 %(n =2 0 )。方法简便实用 ,用于实际样品分析 。
The Cl - in emulsion was determined by ion chromatography. The organic components in the samples were separated by extration method to eliminate the influence on the determination and the contamination of the column. The selectiom of extractant and extracting conditions are discussed. The method has good accuracy and the recovery is 95%～105% with the RSD better than 4.0% (n=20). The test results of practical samples are satisfactory.
