Biosorption of thorium(IV) from aqueous solution by living biomass of marine-derived fungus Fusarium sp. #ZZF51
The biosportion of Th(IV) by the marine-derived Fungus Fusarium sp. #ZZF51 was study. The Biosorption was found to be at a maximum (79.24 %), in a solution containing 50 mg Th/L, at pH 5.0, with 0.28 g dry biomass. The Temkin isotherm model and pseudo-second-order kinetic model was found to fit the data very well over the entire range of concentrations. The FTIR analysis reveals that the carboxyl, amino and hydroxyl groups on the cell wall of Fusarium sp. #ZZF51 play an important role in Th(IV) biosorption process.
