METHOD FOR PURIFICATION OF TECHNOLOGICAL SOLUTIONS AND SEWAGE AGAINST ORGANIC MATERIALS Russian patent published in 1998 - IPC

FIELD: purification of technological solutions and sewage against organic materials which takes place with the help of adsorbents. SUBSTANCE: technological solutions and sewage obtained by hydrometallurgical production of heavy nonferrous metals are purified against organic materials, porous synthetic carbon material being used as adsorbent. Proposed adsorbent may be regenerated by various means. Proposed carbon material represents carbon black being covered with carbon layer having thickness in 100-10000 . Radius of curve of the layer is 100-10000 , its actual density is 1.8-2.1 g/cm³, its X-ray density being 2.112-2.236 g/cm³. EFFECT: improved efficiency of the method. 2 cl, 2 dwg, 4 tbl
