Fusarium sp. #ZZF51, marine-derived mangrove endophytic fungus, was chemically modified by poly(amic acid) to enhance its potential of uranium(VI) biosorption in aqueous solution. Compared with uranium(VI) removal of the pristine biomass, the maximum uranium(VI) adsorption capacity of the modified biomass increased 9.5-fold under the optimal condition of pH 5.0, S/L 0.4, and equilibrium time 180 min. Kinetic study showed that the process follows the pseudo-second-order kinetic model, which indicates that chemical reaction controls the adsorption rate. The thermodynamic experimental data fit we...
