ABSTRACT
Removal of dye Acid Yellow RR, using two different samples of activated carbon by static batch method was studied. Experimental data on optical density of blank solutions of different concentrations ranging from 10 to 100 mg/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 qe adsorbed was calculated. The data was fitted to Polynomial, Langmuir and Freundlich isotherms for two different carbon samples and different concentration and pH values. Constants were calculated from the slope and intercept values of the isotherms. Coefficient of correlation R2 and Standard Deviation SD were also noted. The data fitted well to the isotherms. Carbon sample C1 showed higher potential to adsorb the yellow dye. Adsorption was higher at lower concentrations of the solution. Carbon sample C2 showed better adsorption in acidic pH as com- pared to in alkaline pH. From the analysis of the data it is shown that C2 sample has a good capacity to remove the textile dye from the residue water although sample C1 was still better.
