The article studies petrochemicals and phenols adsorption in static and dynamic conditions from model petrochemical solutions. It was established that the adsorption of resorcinol occurs in micropores by volumetric filling, this process is best described by the Dubinin-Astakhov equation. The adsorption of petrochemicals occurs on the sorbent surface, forming a monolayer, this process is best described by the Langmuir equation. Based on the kinetic curves of petrochemicals and resorcinol adsorption, DEC (dynamic exchange capacity) and FDEC (full dynamic exchange capacity) have been calculated for activated carbons and fibrous sorption material. Using the Shilov equation, kinetic constants of the adsorption dynamics for resorcinol and petrochemicals on various sorbents are calculated. The study proved the promising use of sorbents for wastewater treatment of various industries.
