“Removal of Alizarin Red-S Dye from Aqueous Solution by Sorption on Coconut Shell Activated Carbon”
نویسندگان
چکیده
The removal kinetics and mechanism of alizarin red-s dye, adsorptions on coconut shell activated carbon [CSAC] is studied. The use of low cost ecofriendly adsorbent has been investigated as an ideal alternative to the current expensive methods of removing the dye from aqueous solution. The adsorption removal of Alizarin Red-S dye on CSAC was investigated using batch adsorption technique. The different variables such as initial dye concentration, adsorbent dose, contact time, pH and temperature were determined to optimize the method. The percentage removal of dye was observed to be most effective at pH8 and at contact time 120 min and at an adsorbent dose 4 g/L. The study shows that a CSAC can be an alternative to other expensive adsorbent used for the removal of dyes from aqueous solution. The study indicates that the percentage removal of the dye increases with increase in initial dye concentration; adsorption dose and contact time and attain equilibrium at optimum conditions. The adsorbent was also characterized by FTIR, SEM, EDAX studies. This results shows that, the CSAC is suitable for the removal of alizarin red-s dye from aqueous solution.
