Removal of dyes Reactive Blue 221, N Blue RGB and Acid Blue MTR using two different samples of activated carbon by
static batch method was studied. Experimental data on optical density of solutions at different concentrations ranging from 10
to 100 mg/L and of solutions after adsorption on activated carbon samples were measured. Calibration curves were plotted
and the amount of dye qe adsorbed was calculated. The data was fitted to 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 all the three dyes. Adsorption was higher at lower concentrations.
Carbon sample C2 showed better adsorption in acidic pH as compared to in alkaline pH. From the analysis of the data
capacity of C1 and C2 to remove the dyes from water have been compared.
