Discloses the possibility of using nonionic surfactants in the petrochemical industry. The structures of matter, the value of maximum allowable concentration, are the main quality characteristics. The process of sorption concentration of nonionic surfactant (OP-10) at various sorbents. The main characteristics of the thermodynamics and kinetics of the process. Static sorption isotherms of surfactant from aqueous solutions, calculate the change in enthalpy (О”Рќ) isobaric-isothermal potential (О”G) and entropy (О”S) sorption. The kinetics of adsorption of the surfactant on the considered sorbents from aqueous solutions. The research results obtained during the experiment can be used to simulate the adsorption mechanisms.

Key words: сорбент, сорбция, поверхностно-активные вещества, механизм сорбции, очистка воды, sorbent, sorption, surface-active substances, sorption mechanism, water purification
