Abstract

Mineralogical and chemical compositions of the Almalyk Mining zinc concentrate were studied. Experimental results indicated that sphalerite zinc concentrate can be used as a photocatalyst for decomposition of different reactive textile dyes in water treatment. The photodegradation rate constant increased in following order: Blue SPD>Red SPD>Black B150>Yellow 4GL. The adsorption properties decreased in order Red SPD>Blue SPD> Black B150>Yellow 4GL. Decolorization of dye is not corresponded to COD values of treated dyes solution except Black B150 dye, confirming it’s complete mineralization in aqueous solution
