“…According to the results, the device fully reacts the electrolyte with heavy metal ions in soil, has the advantage of resource reuse and a good removal effect on heavy metal in soil, and is conducive to improving soil remediation efficiency. The effects of amendments, including lime, diatomaceous earth, sodium phosphate, steel slag, and charcoal, were investigated on the immobilization of Cd and found that the lime-diatomaceous earth-charcoal complex exhibited the most favorable repair performance [19]. However, the aforementioned repair approaches possess numerous drawbacks, such as the high cost of physical repair technology, the limited application scope of chemical repair technology, and secondary pollution.…”
