Problems solved by technology

As the soil is easily polluted by chemicals, the polluted soil will not only reduce the yield of crops, but even cause excessive pollutants in agricultural products, endangering human health
[0003] Planting crops on polluted soil will not only affect the growth of crops, thereby reducing crop yields, but also allow crops to absorb the components in the polluted soil during the growth process, causing the crops themselves to be harmed by heavy metal deposition, so that the human body is eating the above crops also have adverse effects

Abstract

The invention discloses a lead metal soil pollution nanometer repairing agent and a preparation method thereof. The lead metal soil pollution nanometer repairing agent comprises, by weight, 50 to 55 parts of bentonite, 20 to 30 parts of mica, 5 to 9 parts of nano-hydroxyapatite, 5 to 8 parts of chitosan fiber, 2 to 4 parts of calcium hydrogen phosphate dihydrate, 2 to 4 parts of carbaldrate, 2 to 3 parts of magnesium carbonate, 1 to 3 parts of trimethylsilyl phosphate, 1 to 2 parts of sodium aluminoferrite, 1 to 2 parts of glutathione, 0.5 to 1 part of calcium aluminate, and 0.5 to 0.8 part of manganese sulfate. The invention also provides the preparation method of the lead metal soil pollution nanometer repairing agent.

Description

technical field [0001] The invention belongs to the field of soil pollution remediation agents, in particular to a lead metal soil pollution nanometer remediation agent and a preparation method thereof. Background technique [0002] Soil is an important material basis for human social production activities and an indispensable natural resource that is difficult to regenerate. Because the soil is easily polluted by chemicals, the polluted soil will not only reduce the yield of crops, but even cause the pollutants in agricultural products to exceed the standard, endangering human health. [0003] Planting crops on polluted soil will not only affect the growth of crops, thereby reducing crop yields, but also allow crops to absorb the components in the polluted soil during the growth process, causing the crops themselves to be harmed by heavy metal deposition, so that the human body is eating the above crops There will also be adverse effects. Lead and its compounds are toxi...
