COLOR REMOVAL FROM TEXTILE WASTEWATER USING CuO NANO-PARTICLE COATED ON SAND, CINDER AND GAC

In this research, batch adsorption studies were carried out using CuO nano-particles coated on the surface of different adsorbents like graded sand, cinder and granular activated carbon (GAC) by ‘Low temperature pyrolysis’ (LTP) method for color removal from textile wastewater. Uncoated and CuO coated adsorbent doses were varied from 1 ? 40 g/L with stirring time of 20 min and stirring speed of 400 rpm. Results showed that CuO coated ad sorbents showed increase in the color removal efficiency than uncoated adsorbents and LTP method was seen to be more successful on GAC than cinder and sand.
