摘　　要：采用《水和废水监测分析方法》(第四版增补版)推荐的亚甲蓝分光光度法测定水中阴离子表面活性剂,优化了试验条件,标准样品测定的相对误差为0.5%,优于方法推荐的2.0%;标准溶液测定的相对标准偏差为2.1%～2.2%,优于方法推荐的2.3%;加标回收率在100%～101%。The methylene -blue colorimetric method was adopted for determining the anionic surfactants in water, which has been recommended by the Water and Wastewater Monitoring Analysis Method （ supplement of the 4th e- dition）. After the optimization of the experimental conditions, the relative error was 0. 5%, superior to the recommended value of 2. 0% by the method. The relative standard deviation ranged from 2. 1% to 2. 2%, superior to the recommended value of 2.3%. The recovery rate was from 100% to 101%.
