Preparation of activated carbon from carbonized rice husk by ozone activation for Cr (VI) removal

Activated carbon (AC) was prepared from carbonized rice husks using ozone as an activating agent. The AC was characterized by nitrogen adsorption, SEM-EDAX and FT-IR. The Brunauer–Emmett–Teller surface area of the carbons was increased from 20 to 380m2/g by the activation. It was observed that the s...
