Biosorption of Foron turquoise SBLN using mixed biomass of white rot fungi from synthetic effluents

Abstract

In the present study, biosorption of Foron turquoise SBLN using mixed biomass of white rot fungi was investigated in batch mode. The effect of process parameters such as pH of solution, medium temperature, biosorbent concentration, dye initial concentration, contact time etc. was investigated for enhanced removal of the dye. Maximum dye removal was observed at pH 2, biosorbent dose, 0.1 g/100 ml and temperature 30°C. The equilibrium data were analyzed by commonly employed Langmuir and Freundlich isotherm equations. The results show that the equilibrium data were better described by Freundlich isotherm model as compared to Langmuir equation. The biosorption kinetic data were found to follow the pseudo-second-order model. The results therefore indicated that mixed biomass of whiterot fungi could be used as natural biosorbent to remove dyes from aqueous effluents.
