ABSTRACT:
The invention relates to a method for removing heavy metal sulphides from dilute aqueous systems as they are present in numerous chemical processes. The method is characterized in that water-soluble polymers such as polyethyleneimines, homopolymers or copolymers of derivatives of acrylic acid or methacrylic acid or homopolymers or copolymers of styrenesulphonic acids are added to said systems and the systems are then filtered.
