Adsorption of 4-Chlorophenol onto Activated Carbon Prepared from Wheat Straw: Equilibrium Study

Abstract:

The adsorption studies of 4-chlorophenol from aqueous solution on activated carbon derived from wheat straw (WAC) have been performed. Several experimental parameters like initial pH, p-CP concentration and solution temperature were evaluated. Solution pH within 2-8 is favor of adsorption and it is disadvantage of adsorption at higher temperature. Langmuir and Freundlich isotherm models were used to fit the experimental data and Langmuir was better. The maximum capacity was 64.8 mg g–1 at 293 K. The process is spontaneous and exothermic and physical action is major mechanism.
