PROCESS FOR PROCESSING OF HIGHLY TOXIC SUBSTANCES AND BINARY SYSTEMS IN TIN AND LEAD COMPOSITION OF RINSE WATER OF ELECTROPLATING INDUSTRY

摘要

A process for processing of highly toxic substances and binary systems in tin and lead composition of rinse water of electroplating industry by their treatment with sulphide-alcaline wastes of petrochemical industry with further extraction of sludge by filtering. As petrochemical wastes the spent sulphide-alcaline solutions of treatment of crude oil are used. The total stoichiometric quantity of tin (II) and lead (II) ions is added. The reaction mixture is mixed to complete precipitation of tin (II) sulphide and lead (II) sulphide.
