摘要：

This study developed recyclable magnetic layered double oxide beads (Mag-LDO) for composting with heavy metal-contaminated soil and agricultural waste, aiming to reduce heavy metals (HMs) concentration and bioavailable forms, enhance humification, and elucidate the underlying mechanisms. Results showed that a 5% addition of Mag-LDO increased humic acid (HA) formation by 16.02% and significantly reduced total Cd and Pb by 18.38% and 21.93%, respectively, compared to the control group. Moreover, it effectively reduced BF-Cd and BF-Pb by 16.31% and 10.37%, respectively. These results demonstrated...
