Effects of various Carbonization Processes in the Preparation of Nanoporous Carbon Materials using Ipomoea Carnea Stem Waste for the Removal of Dyes from Textile Industrial Effluents

Nanoporous activated carbon materials were prepared from abundantly available Ipomoea Carnea stem waste. A series of five Nanoporous carbon samples were prepared by subjecting the carbon material to various chemical processes. The physico-chemical properties and adsorption capacities were compared. These materials accumulate superior properties and good adsorption behaviours. The adsorption capacity of selected derived carbon sample using Ipomoea Carnea stem waste prepared by Dolomite process was much greater than the capacities of the other carbons prepared by various processes viz., Acid process, ZnCl2 process, Sulphate process and 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, its isoelectricpoint (ZPC), surface area, iodine number etc.
