摘要：It was studied process of elimination of direct red dye in the presence of anionic surfactant (sodium lauryl sulphate)of model solution, with their combinated tratation with aluminium coagulant, catalytic oxidation with hydrogen peroxideand sorbtion of remain compounds from activated charcoal by depending of concentration of aluminium ions, dye,surfactant and time of catalytic oxidation.It was obtained that direct dye can be eliminated from model solution with initial concentration of dye from 50 to200 mg/l in presence of anionic surfactant (only to 40 mg/l) by applyind of combinated methods of coagulation withaluminium coagulant and adsorbtion from activated charcoal. Consume of coagulant in presence of surfactant rise from2-3 time comparated with removal of dyes in absence of surfactant. It was founded that catalytic oxidation the mixtureof direct dyes and anionic surfactants, molecules of surfactant degrades more difficult than dye molecules at the catalyticoxidation in presence of hydrogen peroxide, catalysed by Fe (II), and concentration of remain organic compouds can bereduced only on adsorbtion by activated charcoal. Cleaning concentrated solution, that contain direct dye and anionicsurfactant with 200 mg/l and 60 mg/l concentration, can be realize only with combination of coagulation, catalyticoxidation and adsorbtion with activated charcoal methods
