文摘
- •
No experimental liquid phase speciation changes for selenium were observed.
- •
Selenite retention exceeded the retention of selenate in Olkiluoto soil.
- •
Weakly crystalline Al and Fe oxides were more important sorbents than organic matter.
- •
Fe and Al bearing minerals biotite, hematite and chlorite showed sorption of selenite.
- •
Selenate was not retained by any of the studied minerals.
