DETERMINATION OF HEXAVALENT CHROMIUM ADSORPTION KINETICS AND EQUILIBRIUM ISOTHERMS IN AQUEOUS SOLUTIONS CONTAINING ACTIVATED COCONUT SHELL CHARCOAL
Hexavalent chromium has toxic and carcinogenic effects and is often found contaminating in surface waters. In the present study, coconut shell charcoal (CSC) thermally and chemically activated with acetic acid was used for the removal of Cr(VI) from aqueous solutions. The increase in temperature reduced the adsorption capacity, indicating exothermic adsorption. Adsorption kinetics was best analyzed for pseudo-second order model exhibited the best correlation coefficient (R
