Спосіб переробки високотоксичних речовин і бінарних систем у складі стануму та цинку промивних вод гальванічних виробництв

Abstract

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