文摘
- •
Alkali-activated slag cement exhibited effective immobilization for Cr(VI).
- •
The chromium leachability depended on the final leachate pH.
- •
Cr(VI) was reduced to Cr(III) by AAS without any additional reductants.
- •
The CrO4-U phase was formed as the primary retention phase for unreduced Cr(VI).
