[0002] Heavy metal contaminated soil is a phenomenon in which the content of trace harmful elements in the soil exceeds its natural background value due to human activities, which has a negative impact on the soil ecosystem. Heavy metal contaminated soil may interfere with the activity of soil microorganisms and affect the ecological balance of the soil. Excessive heavy metals will cause plant growth to be hindered.

[0021] It should be noted that heavy metal contaminated soil is a phenomenon that due to human activities, the content of trace harmful elements in the soil exceeds its natural background value, which has a negative impact on the soil ecosystem. Heavy metal contaminated soil may interfere with the activity of soil microorganisms and affect the ecological balance of the soil. Excessive heavy metals will cause plant growth to be hindered. At the same time, heavy metals accumulate through the food chain and accumulate in crops, thereby affecting food safety and causing damage to human health. Magnetic separation of heavy metal contaminated soil is a method of using magnetic materials to adsorb and separate heavy metals in the soil. The selective adsorption capacity of magnetic materials for heavy metal ions is used to separate magnetic materials loaded with heavy metals from the soil through magnetic separation technology, thereby achieving soil repair.
