文摘
- •
Biosorption of uranium onto Eichhornia crassipes is strongly pH dependent.
- •
Langmuir isotherm and pseudo-second-order kinetics best describe U(VI) biosorption.
- •
The U(VI) biosorption onto E. crassipes is spontaneous and endothermic.
- •
Coordination and ion exchange mechanisms could be involved U(VI) biosorption.
