Abstract : In this study, removal of direct blue dyestuff (an organic pollutant) from wastewater effluents of textile industry by adsorption was investigated. Activated charcoal was produced from sawdust using aqueous zinc chloride, ZnCl2 as the activating agent and carbonized at 500 0C for 45 minutes. The effectiveness of the AC was measured in terms of absorbance using colorimeter. The results show a very sharp reduction from 600 mg/dm3 to 40 mg/dm3. Experimental results were subjected to Langmuir and Freundlich adsorption isotherms, Langmuir model was better fitted for the equilibrium analysis with R2 value of 0.917 and physical adsorption type. The values of the dimensionless constant separation factor, RL lies between 0 and 1, thus indicate that the decolourization process is favorable.
