Effect of Various Carbonization Processes in the Preparation of Nanoporous Carbon Materials using Albizia amara Pod Shell Waste for the Removal of Dyes from Textile Industrial Effluents
J. Environ. Nanotechnol., Volume 3, No 4 (December 2014) pp. 112-122
Abstract
Activated carbon materials were prepared from abundantly available Albizia amara pod shell waste. A series of five nanopaorous carbon samples were prepared by subjecting the carbon material to various chemical processes. The physic-chemical properties and adsorption capacities were compared. These materials accumulate superior and good adsorption behaviours. The adsorption capacity of selected than the capacities of the other carbonate process. The dye removal from textile industrial effluents by nanoporous carbon adsorption is mainly due to the surface action between the anionic or cationic nature of the dye and the acidic or basic functional groups. Present on the surface of the carbon material iso-electric point (zpc) surface area iodine number etc. This concept of surface action has been cudeley recognized and the effective usage of the carbon adsorbent has shown new dimensions in studying the adsorption characteristic. The influence of surface area and porosity of the carbon samples on dye removal was analysed. The use of surface modified and chemically treated activated carbons derived from the stem wastes of Albizia amara was extensively of dyes. The effects and influence of pKa values of dues and isoelectric point (pHzpc) of nanoporous carbon materials. The results reveal the prepared activated carbon caused by employed as a low cost alternative for removing toxic and carcinogenic dyes from the textile industrial waste water.
