Abstract: Removal of dye Green B using two different samples of activated carbon by static-batch method and continuous process was studied. Experimental data on optical density of blank solutions of different concentrations ranging from 10 to 100mg/L and optical density of solutions after adsorption on activated carbon samples were taken and analyzed. Calibration curves were plotted and the amount of dye adsorbed was calculated. The data was fitted to Langmuir and Freundlich isotherms for two different carbon samples and concentration values. Constants were calculated from the slope and intercept values of the isotherm. Coefficient of correlation R2 and standard deviation SD were also noted. The data fitted well to the isotherms. Carbon sample C1 showed considerably higher potential to adsorb the dye Green B as compared to carbon sample C2. Adsorption was better in batch process in respect to continuous flow method. From the analysis of the data it is shown that both activated carbon samples had a good capacity to remove the textile dye from the residue wastewater.
