In this study, a magnetic amorphous titanium phosphate material was successfully synthesized and evaluated for U(VI) removal through adsorption. The experimental results showed that the material had a high adsorption capacity for U(VI) under optimal x and T conditions, and the adsorption process followed a pseudo-second order kinetic model.
The material of magnetic amorphous titanium phosphate (MATP-x-T, where x was the dosage of Fe3O4, T was synthesis temperature) was successfully synthesized and confirmed by various experimental characterization methods (FT-IR, XRD, SEM, and Zeta potential), and its adsorption property for U(VI) removal was evaluated. The adsorption of U(VI) on MATP-x-T were explored through batch experiments. The optimal value of x and T was 0.5 g and 70 degrees C, respectively. The saturated adsorption capacity of MATP-0.5-70 was 401.5 mg g(-1) for U(VI) at 298.15 K. The U(VI) adsorption was well explained by the pseudo-second order kinetic model. The possible mechanism of the adsorption of U(VI) was explored based on XPS and FTIR analysis. MATP-0.5-70 could be employed as an auspicious candidate for U(VI) removal radioactive wastewater.
