Abstract
The feasibility of activated carbon derived from Palmyra shell (PSAC) to eliminate Methylene Blue (MB) dye from synthetic textile effluent was considered through batch mode studies. Experiments were conducted by varying several parameters namely initial concentrations of dye, Interaction time, adsorbent dose and pH of the dye solution to ascertain optimum conditions. The optimum conditions for the cent percent removal of dye were found to be initial concentration: 55 ppm, Contact time: 50 min, adsorbent dose: 5 g/L and pH: 10. Kinetics studies of the adsorption revealed that removal of dye follows first order kinetics. The isotherms for the adsorption of dye on to the PSAC fit the Freundlich and Langmuir isotherms quiet well. The Scanning Electron Microscope (SEM), Energy dispersive analysis of X-Ray (EDX) and FT-IR images of PSAC before and after adsorption confirmed that the uptake of dye by Palmyra shell activated carbon.
