摘要
采用偶氮红两相滴定法测定水中阴离子表面活性剂,有效地消除了环境水体中硬度、蛋白质、淀粉及非离子表面活性剂的干扰。其平均回收率为100.6％,相对标准偏差为1.0％。
The method for determining anionic surfactants in water by two-phase titration with azophloxine was presented, interferences with hardness, protein, starch, nonionic surfactants etc. existing in water body were eliminated. In comparsion with spectrometric method, operation was simple and quick, and result was accurate. The average recovery rate was 100.6％ and relative standard deviation was 1.0％ (n=11).
