| Abstract: | 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%. |
| Keywords: | anionic surfactants environmental monitoring methylene - blue colorimetric method optimization |
