Modification of Surface Properties of Lentinus sajor-caju Mycelia by Physical and Chemical Methods: Evaluation of Their Cr super(6+) Removal Efficiencies from Aqueous Medium

Hexavalent chromium biosorption from aqueous solution onto untreated and heat-, acid-, and alkali-treated Lentinus sajor-caju mycelia was researched. Biosorption equilibrium was attained in about 4 h, and the surface charge density of the fungal preparations varied with pH. Maximum absorption of Cr...

Description
Summary:Hexavalent chromium biosorption from aqueous solution onto untreated and heat-, acid-, and alkali-treated Lentinus sajor-caju mycelia was researched. Biosorption equilibrium was attained in about 4 h, and the surface charge density of the fungal preparations varied with pH. Maximum absorption of Cr ions was obtained at pH 2.0; biosorption increased as the initial concentration of C in the medium increased. Maximum biosorption capacities of 0.363, 0.613, 0.478, and 0.513 mmol Cr/g of dry biomass were recorded for untreated and heat-, hydrochloric acid-, and sodium hydroxide-treated fungal materials, respectively.
