RICE HUSK AS DYES REMOVAL FROM IMPREGNATED COTTON WASTES GENERATED IN SPORTS INDUSTRIES OF SIALKOT, PAKISTAN

Abstract

The current study was designed to the potential dyes removal present in solid wastes of cotton (Generated from sports industries). Sport products were colored with different shaded dyes with the help of cotton that are disposed to the different environmental compartment. Cost effective and eco-friendly adsorbents (rice husk) has been collected and used as an ideal alternative to the conventional method of dyes removal for disposed cotton wastes. The effect of pH, contact time, adsorbent dose, shaking speed and amount of dyes solution of rice husks on dyes removal have been evaluated and optimized. Maximum and efficient dyes removal was observed at pH (3.0), contact time (240 min), adsorbent dose (8.0 g), shaking speed (300 rpm) and amount of dyes solution (200 ml). All these conditions have ensured dyes removal up to 91, 93, 92, 90 and 93% respectively. This process highlighted the advantage of recovery of methyl ethyl ketone (MEK) and dyes which may be used again after modification. Furthermore the present study encourages that the rice husks generated as biological waste can be used as promising tool for dyes removal.
