Biosorption of Malachite Green, Safranine T and Methylene Blue onto Spent Substrate of Flammulina Velutiper
Spent substrate of Flammulina velutipes (SSFV) was firstly used as a bio-adsorbent to adsorb malachite green, safranine T and methylene blue in aqueous solution, and the adsorption thermodynamics and kinetics were also studied. Langmuir and Freundlich isotherm models fit well the adsorption data, and the maximum adsorption capacity of SSFV for malachite green was 30.77 mg/g. Adsorption of the dyes onto SSFV was a spontaneous exothermic process based on adsorption thermodynamics model. SSFV could absorb the dyes rapidly and achieve equilibrium in a short time, and the data fit well with second-order kinetics model. The results suggest that SSFV should be an economical and efficient bio-adsorbent for the three dyes.
