Phenol Removal from Aqueous System by Jute Stick

Abstract

The adsorption technique using jute sticks has been applied for the removal of phenol from aqueous solutions. The extent of removal was dependent on concentration of phenol, contact time, pH, and quantity of adsorbent. With an initial concentration of 40 ppm phenol in 100 mL and pH 10.0, the removal was found to be about 68% with 3.0 g jute stick. The time to reach equilibrium was found to be 5 hr. The applicability of Freundlich isotherm to the adsorption of phenol system was tested at 25 0C to 40 0C at pH 10.0. The spent adsorbent was regenerated by acid treatment.
