FIELD: liquid waste treatment.
SUBSTANCE: invention provides complexion structure containing conducting or semiconducting substrate, to which organic polymer film is grafted containing monomer selected from 4-vinylpyridine and vinylbipyridine plus cross-linking agent, namely divinylbenzene. Preparation method includes step, in which above electrically neutral organic polymer is grafted, said polymer being able of complexion ions via electropolymerization while electric grafting is performed on conducting or semiconducting substrate in presence of above cross-linking agent.
EFFECT: enhanced waste treatment efficiency.
