چکیده انگلیسی
Spent substrate of Ganodorma lucidum (SSGL), waste from cultivation of Ganoderma lucidum, was firstly used as a bio-adsorbent to adsorb three typical dyes malachite green, safranine T and methylene blue, and the adsorption thermodynamics and dynamics were also studied. SSGL was rich of hydroxyl group and carbonyl group, which had the potential to be an efficient bio-adsorbent for the three dyes removal from water and wastewater, and the treatment model should be eco-friendly. The experimental data fit well with the Langmuir and Freundlich isotherm, and the adsorption of dyes took place mainly on monolayer surface of SSGL. The experimental data fit also well with the adsorption thermodynamics, the adsorption were spontaneous and mainly a chemical adsorption. SSGL could adsorb the dyes rapidly and achieve an equilibrium in a short time, and the experimental data fit well with the second-order kinetics model.
