Abstract

Low cost adsorbents derived from wastes have demonstrated outstanding capabilities for the removal of dyes from wastewater. In the present study, fruit of Cordia Sebestena, a gardening plant material was used for the preparation of Activated Carbon. Activated carbons from the fruit of Cordia Sebestena were prepared by physical and chemical processes such as impregnation of raw material with Conc.H2SO4, KOH, ZnCl2, H3PO4 solution, direct pyrolysis, dolomite process, chemical activation with H2SO4 +H2O2 solution respectively followed by activation at 8000C.The physico- chemical characteristics such as moisture content , volatile matter, pH, conductivity, bulk density, specific gravity, porosity , methylene blue number, iodine number and SEM were investigated to study the adsorptive capacity. Among the prepared activated carbons, CSAC with H3PO4 solution followed by activation at 8000C possess high surface area and more porosity and was chosen as best adsorbent for the removal of dyes from textile industry effluent.
