SYNTHESES AND USING OF ACTIVATED CARBON FROM RICE HUSK AND PURE SILICA FOR POLLUTION REMOVAL PROCESS

Abstract

Activated carbon Rice Husk ACRH and Silica powder of Rice Husk SRH has been successfully synthesized from Iraqi Rice Husk RH through physical and chemical activation processes using potassium chloride KCl and N2 gas as activating agents, and carbonized for production of activated carbon at 500C0 for 2hrs. The production of activated carbon (AC) appeared to be one of the most important phases of this study. SRH was carried out by treatment with acidic and basic solution and pyrolysis at 500 Co for 2hrs. Three kinds of adsorption materials was studyed with the removal of polluted water (RH , ACRH and SRH) . FT-IR, UV-Visible Spectra were performed for characterized and studying adsorption, which calculated with using an Langmuir and Freundlich Equations. Frandash equation isotherms was largely applied or fitted on the behavior of adsorption processes.
