FIELD: process engineering.
SUBSTANCE: invention relates to treatment of whatever effluents for removal of contaminants, namely, lead and cadmium, and may be used in treatment of effluents produced in electroplating, production of plastic materials and paint-and-varnish industry. White sludge, a product of autoclave removal of silicon from aluminate solutions of alumina production, is used as a sorbent for removal of lead and cadmium compounds from effluents. Lead and cadmium sorption is carried out on mixing liquid phase containing said compounds for 6-32 h.
EFFECT: efficient treatment of effluents by inexpensive sorbent.
