A study of the process of ultrafiltration separation of a solution containing an anionic surfactant on membranes of different types: cellulose acetate and polysulfonamide was carried out. It was found that the material of the active layer of the composite membrane has a significant effect on the ultrafiltration separation of such solutions. High values of the retention coefficient during ultrafiltration separation of solutions containing anionic surfactants were obtained in dilute solutions.
