Removal of Phenol from Aqueous Solution Using Sugar Beet Pulp Activated Carbon

Abstract

In this study, activated carbon was obtained from sugar beet pulp by applying low-temperature carbonization at 350 degrees C. Removal of phenol from aqueous solutions was investigated by applying chemical activation process to activated carbon with HCl and NaOH. For adsorption of phenol removal from aqueous solutions; effects of pH, adsorbent dosage, phenol concentration, temperature and contact times were investigated. The highest removal efficiency was achieved as 63 % at pH of 7 for NaOH-treated activated carbon at 0.1 g adsorbent dosage, 100 mg/L phenol concentration, 1 hour contact time, and room temperature. Results of the experiments showed that the adsorption kinetics obey pseudo-second order kinetic model, respectively.
