As a result of oxidative dehydropolycondensation of aniline on the surface of polymer materials, effective composite sorbents were obtained that can absorb bichromate ions from solutions. The optimal content of polyaniline was determined, which allows achieving the specific sorption capacity of composite structures of 1.49 mg-EQ/g and the degree of extraction of highly toxic chromium of 99.74 %. The developed composite sorbents have high kinetic parameters and can successfully solve the problems of treatment of waste water solutions of galvanic production.
