In the present investigation chemical oxygen demand and color removal of pulp and paper mill effluent, by adsorption on formaldehyde treated activated keekar bark was studied at varying the pollutants concentrations, adsorbents dose, pH, and agitation time in a batch reactor. The activated keekar bark was prepared thermally in size 0.3 mm. The COD reduction was found maximum at alkaline pH (10), where as color removal was observed at a low pH (2) with a adsorbent dose of 20 mg/L. The amount of pollutants adsorbed increased with increase in dose of both adsorbents and their agitation time, higher reduction of COD and color removal was possible provided the low initial concentration. Thus it is proposed that AKB can be potential adsorbents for pollutants removal from the pulp and paper mill effluent and easily available in country side at low cost.
