Sequestration of Cr(VI) by the Activated Carbon prepared from Coffee husk(CHAC)

Awugchew Teshome Ayele, S. Anuradha Jabasingh, Aynalem Abebe

Abstract


The potential of Coffee husks for the production of a low-cost activated carbon (CHAC) was investigated in this study. During the synthesis of the adsorbent, the concentration of the activating agent (H3PO4), impregnation ratio, carbonization temperature and holding time were optimized by Response Surface Method (RSM) using Box-Behnken design. Further, the application of coffee husk activated carbon for Cr (VI) adsorption from aqueous solution was investigated.

Keywords
