Effect of activation agents on cod reduction using activated carbon from agricultural residue

Abstract

This study investigated the effect of activating agent on activated carbon preparation and potential chemical oxygen demand (COD) reduction using activated carbons (AC) prepared. Zinc chloride, phosphoric acid and potassium hydroxide were utilized in impregnation of bamboo and rice husk. Result of SEM-EDX, FTIR as well as COD reduction were compared and discussed. The SEM displayed highest porosity in AC using KOH activation. FTIR analysis displayed obvious difference for each activation. AC using KOH activation obtained highest COD reduction.
