Adsorption of Chromium from Aqueous Solution Using Activated Carbon Coated Sand

摘要

Activated carbon coated silica sand (AC@sand) synthesized by hydrothermal carbonization and KOH activation was used to adsorb chromium from aqueous solution. The factors which influence the removal of Cr(VI) onto the AC@sand including the pH, initial concentration, contact time and temperature was studied. The pH and temperature influence both adsorption and reduction.
