Adsorption performance and mechanism of MoS2/BC composite for U(VI) from aqueous solution
A molybdenum disulfide/biochar (MoS 2 /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 MoS 2 /BC exhibit a saturated adsorption capacity of 451.3 mg/g at pH = 5, t = 60 min, T =...

/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 MoS
2
/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,
C
U(VI)
= 10 mg/L, which was higher than that of MoS
2
and biochar. The process of MoS
2
/BC for U(VI) adsorption was better simulated via the pseudo-second-order kinetic model (
R
2
= 0.999) and Langmuir isotherm model (
R
2
= 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%. |
