Abstract: In this paper "a new response equation of Non-Nernst range of electrodes is derived and a quantitative analysis method is established. This method makes the electrode to be used to measure content of anionic surfactant in drinking water and surface water. The results show that the method would replace methylene blue colorimetric method.

Key words: Anionic surfactant, Electrode, Non-Nernst range
