A biosorbent prepared from powdered mycelial biomass of Ceriporia lacerata (CLB), a basidiomycetous fungus, was applied for the uptake of Crystal Violet from aqueous solution. A batch adsorption experiment was used for the biosorption process, involving effect of experimental factors and biosorption kinetics and equilibrium. Biosorption process showed that the removal of Crystal Violet by CLB was effective over wide pH range, and meanwhile was independent on ionic strength. Biosorption capacities of CLB increased with the initial dye concentration increasing, due to an increase in the driving force of the concentration gradient. The adsorbed Crystal Violet amount per unit biomass weight decreased with increasing biosorbent dosage, due to the splitting effect of flux (concentration gradient) between sorbate and biosorbent. A maximum sorption capacity of 239.25 mg/g was observed. Biosorption kinetics was found to be best represented by the pseudo second-order kinetic model. The equilibrium adsorption data was well described by the Koble-Corrigan model. FT-IR (Fourier Transform Infrared Spetroscopy) spectrum showed the presence of O-H, COOH, C=O, C-N, C-H, -NH2 and P-OH in the surface of CLB as functional groups. This study showed CLB can effectively remove CV from dye wastewater.
