Abstract (en)
[origin: EP0049656A1] 1. Purification device for removing heavy metal contaminants from aqueous effluents, characterized in that it comprises a crosslinked hydrophilic copolymer support derived from 85 to 95% by weight of a hydrophilic monounsaturated monomer and 5 to 15% by weight of a polyunsaturated monomer, and an agent capable of complexing heavy metals incorporated in said support in an amount from 2 to 20% by weight, based on total weight of agent and support, said agent being selected from 2-thiobenzimidazole, chloro-, nitro- or dimethyl derivatives of 2-thiobenzimidazole, 2-thio-3-vinylbenzimidazole, thioureidobenzimidazole, 2-aminobenzimidazole and guanidines.
