Abstract
- Modifications of red mud for activating available silicon (Si) by phosphates were carried on in this paper. And then the modified red mud materials were used to stabilize Cd in an ore soil. Results indicated that phosphates efficiently increase the content of available Si in red mud. In the stabilization, exchange Cd was decreased by 90.97% when using 5% potassium dihydrogen phosphate modified red mud, which was better than using raw re mud as the decrease was 77.08%. In rice pot soil, increases of residue Cd were positively correlated with the increases of available Si (P
