摘要：

The adsorption capacity of the water hyacinth-derived biochar on U(VI) was investigated in this study. The as-prepared sample was characterized by methods of SEM, XRD, XPS, FT-IR and BET. Functional groups on the biochar surface could undergo complexation with U(VI). Effects of adsorption dose, temperature, contact time, solution pH and ionic strength were studied by static batch experiments. Results show that the adsorption could be better fitted by the pseudo-second-order kinetic equation and Langmuir model. The solution pH has a great impact on the U(VI) adsorption, while the ionic strength exerts no significant effect.
