N2 - The widespread use of anionic surfactants leads to significant environmental pollution. It is known that they can interact with basic biopolymers and are soluble in fats, so this class of compounds cannot be inert towards living organisms; on the contrary, many facts indicate danger for them. In this regard, an important task is to control the concentration of anionic surfactants in environmental objects, primarily in water bodies. In the presented work, a method for the quantitative analysis of anionic surfactants was developed using sodium laurate as an example. The essence of the method was the extraction of a surfactant complex with a methylene blue indicator into chloroform, re-extraction of the indicator into an aqueous solution of sulfuric acid, followed by voltammetry. Also, to implement the method, a design of the kit has been proposed, which in the future will allow analysis in the fields. The appearance of such a method using this equipment will make it possible to analyze water bodies without wasting time on delivering samples to the laboratory, which will have a positive impact on environmental monitoring.
