Adsorption Properties of Dyeing Wastewater on 8-Hydroxyquinoline Modified Bentonite

Abstract:

Article Preview

A novel adsorption material was synthesized and characterized by the methods of X-ray diffraction and scanning electron microscopy. The optimum reaction conditions of the 8-hydroxyquinoline modified bentonites were studied. And the modified bentonite was applied into the treatment of dyeing wastewater. The decoloration rate was invested as index. The effects of pH, adsorbent dosage, stirring speed, sedimentation time on adsorption have also been studied. The result showed that the decoloration rate of direct light turquoise blue dye on modified bentonites reached 94.12%, and the decoloration rate of acid orange dyeing wastewater reached 74.46%. So this type of modified bentonite was suitable for the treatment of dyeing wastewater.
