Biosorption potential of Talaromayces aculeatus
AMDC-14 (KF588645) 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), time
(15-1440 min), dye concentration (10-200 ppm) and 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.
