CHEMICALLY TREATED SAW DUST AS ADSORBENT TO REMOVE PHENOL FROM WASTEWATER

The capability of saw dust as an adsorbent was tested to adsorb phenol from wastewater. The property of the saw dust was improved by treating with sulphuric acid. The effect of operating parameters like dosage and pH were investigated. The isotherm studies were conducted by varying temperature in the range of 25oC, 35oC and 45oC. The kinetic experiments were conducted for the concentrations of 60, 90 and 120 mg/L. The isotherm data were following Freundlich model and the kinetic experiments were agreeing with first order model. The maximum adsorption capacity was calculated as 9.025 mg/g.
