TALAROMYCES ACULEATUS FROM ACIDIC ENVIRONMENT AS A NEW FUNGAL BIOSORBENT FOR REMOVAL OF SOME REACTIVE TEXTILE DYES
Abstract :
Biosorption potential of Talaromayces aculeatus AMDC-14 (KF588646) as low-cost biosorbent for different dyes (Reactive Blue 13, Reactive Blue 72, Reactive Yellow 85 and Reactive Orange 13) removal from aqueous medium was studied. Experiments were performed to determine effect of initial solution pH (1-7), biosorbent dose (0.1-2.5 g L^-1), contact time (15-1440 min), dye concentration (10-200 ppm), temperature (25-40 °C) onto Talaromayces aculeatus biosorption. Biosorption equilibrium data were described very well for Reactive Blue 13, Reactive Blue 72, Reactive Yellow 85 and Reactive Orange 13 by Langmuir isotherm model than Freundlich isotherm model with maximum biosorption capacities which are 32.10, 71.30, 20.67 and 31.30 mg g^-1, respectively. Biosorption of investigated dyes fitted to kinetic model of pseudo-second-order for all dyes. Gibbs free energies (ΔG°) of biosorption processes were calculated and the results indicated that all selected dyes biosorption onto Talaromayces aculeatus AMDC-14 were spontaneous in this study. And also biosorption processes had endothermic enthalpy values except Reactive Blue 72.
