文摘
- •
The leaching of montmorillonite in aqueous solutions at different pH.
- •
The evaluation of Ce(III) uptake on montmorillonite using different isotherm and ion exchange models.
- •
Formation of Ce(IV) complexes on montmorillonite with very strong binding is proved and quantitatively determined.
- •
The different mechanisms of Ce(III) and Ce(IV) fixation on montmorillonite give significantly different quantitative cerium uptake.
