Biosorption of phenol by dried biomass

Abstract

The adsorption of phenol onto dried biomass was studied as a function of initial phenol concentration, temperature, and particle sizes. The maximum phenol adsorption yields were obtained at the temperature of 30°C, the equilibrium uptake increased with increasing initial phenol concentration and the best adsorbed amounts were obtained for particle sizes between 0.05 and 0.40 mm for biomass Pleurotus Mutilus. The Freundlich and Langmuir adsorption models have been used for the mathematical description of the adsorption equilibrium. The results show that experimental data fit perfectly the Langmuir model.
