Manganese ferrite/porous graphite carbon nitride composites (MnFe2O4/porous g-C3N4[PCN]) were synthesized by template-assisted thermal polymerization and hydrothermal method and applied for high adsorption of U(VI) from aqueous solution. Results indicated that the maximum adsorption capacity of MnFe2O4/PCN (MPCN) was 367.9mgg−1 under optimum conditions (pH = 5, t = 15min, and T = 308K), which was higher than that of g-C3N4 (185.1mgg−1). Adsorption was well fitted with Langmuir isotherm model and pseudo-second-order kinetic equation. Thermodyn...
