Abstract
A molybdenum disulfide/biochar (MoS2/BC) composite was synthesised by a facile hydrothermal process and used for the adsorption of U(VI) from aqueous solution through batch experiments. Results showed that MoS2/BC exhibit a saturated adsorption capacity of 451.3 mg/g at pH = 5, t = 60 min, T = 298 K, M/V = 0.02 g/L, CU(VI) = 10 mg/L, which was higher than that of MoS2 and biochar. The process of MoS2/BC for U(VI) adsorption was better simulated via the pseudo-second-order kinetic model (R2 = 0.999) and Langmuir isotherm model (R2 = 0.999). The adsorption mechanism of U(VI) includes chemical adsorption, electrostatic attraction, surface complexation of oxygen-containing functional groups, cation-π bond and coordination of S group. After five adsorption–desorption experiments, the elimination rate remained above 80%.
