摘要：The study deals with utilization of an agricultural by-product, risk husk for the removal of ChemicalOxygen Demand (COD) from sewage. Rice husk was processed into Rice Husk Activated Carbon (RHAC), a moreuseful form, by using phosphoric acid. The characteristics of raw sewage like pH and initial COD and thecharacteristics of adsorbent were measured. The mechanism of removal of COD by adsorption onto RHAC was studiedby Batch process, under varying adsorbent dosage and pH of the solution to find the optimum conditions. RHAC wasfound to remove 92.37 % COD at dosage 5 gm and pH 6
