Abstract

This work investigated the applicability of activated carbon prepared from local rice husk as adsorbent for effective removal of Congo red dye from aqueous solution. The study considered an agro based waste material which otherwise could be disposed, is employed and its efficiency in the removal of dye substance from contaminated wastewater was tested. The adsorbent was characterized using FTIR spectroscopy. The effects of physical parameters such as carbon content, moisture and pH values, bulk density and operational parameters which include, dye concentration, adsorbent dosage, contact time were investigated with respect to dye removing efficiency. The result showed that efficiency of dye adsorption on the adsorbent range from 34.30 to 83.35% within temperature values of 35 to 65oC.The results further indicated that, adsorption efficiency of the dye increases as contact time changed from 5 to 90 minutes, then became constant.
