The presence of surfactants creates problems in the purification of industrial wastewater and suppresses the processes of self-purification when they enter the natural surface water bodies. Sorption methods are relatively inexpensive in use and allow the content of pollutants to be reduced to low concentrations. In this paper, for the removal of surfactants it is suggested to use a sorbent with oxidizing properties. The composite sorbent based on activated charcoal Filtrasorb 300 was obtained, in which the MnO 2 crystals were precipitated by the treatment of coal with a potassium permanganate solution. Sulfonol NP-3, which is widely used as a damping, washing and emulsifying agent, was used for preparation of model solutions. The study of the influence of the concentration of the permanganate solution, the duration of the treatment, as well as the duration of contact of the obtained sorbent with the model solutions of surfactant on the degree of reduction of the concentration of sulphonol has been carried out. Sorption isoterms of sulfonol NP-3 on the initial coal and obtained composite sorbent were obtained. For comparison, the results of research on the oxidation of sulfonol NP-3 using a suspension of MnO 2 are given. Due to the larger contact surface, the use of composite sorbent allows faster reduction of the content of sulfonol and reaching lower concentrations. The method is suitable for post-treatment of industrial waste water before returning to a recycling cycle or before dumping in natural reservoirs.
