Abstract
The effects of pH, contact time and adsorbent concentration on the adsorption of Cr (VI) onto raw rice husk have been investigated. The parameters -raw rice husk (RRW) particle size which was in the range of 450-600 urn, concentration from 10g/I to 70g/l, contact time 0.5 10 2.0 hours, and pH 1-8 were tested using 50mg/1 solutions of Cr (VI). The maximum removal efficiency was 66.6% for RRW concentration of 70g/l, at pH 2 and 2 hours contact time. In terms of adsorption capacity, the 109/I adsorbent concentration gave the highest reading of 2.2 mg/g for a pH of 2 and 2 hours contact time.
