Abstract
Hexavalent Chromium is highly toxic and carcinogenic. It is extensively being used in electroplating, textile and tannery industries. Present investigation was an attempt to find low cost hexavalent chromium adsorption using different saw dust in a lab-scale adsorption column. Results indicated 94.1%, 66.04%, 88.03% and 80.04% reduction of chromium concentration by Sakhu (Shorea robusta), Sheesham (Dalbergia sissoo), Eucalyptus (Eucalyptus globules) and Mango (Mangifera indica) saw dusts respectively; at 25 oC and retention time of 40 minutes with flow rate 0.1 mL/sec.
