Abstract

The concn of anionic surfactants in alkaline media has been determined by modification of the methylene blue titration. The method is based on the oxidation of methylene blue chloride to dimethylthionoline, a red dye, in the presence of chloroform and sodium hydroxide. This method in conjunction with the acid methylene blue titration, also may be used to determine the amt of amine oxides in formulated products. For concns of less than 100 ppm a spectrophotometric method was used.
