[0005] CN20031010891.0 discloses a chemical regulator to control soil pollution, the main component is low molecular weight chitosan, its main function is to use as a washing agent, CN20121023142.2 discloses a heavy metal adsorption flocculant, mainly used Adsorbs flocculants in water bodies. Although these chelating agents can chelate metals well, heavy metals will still remain in the soil after chelation, and will be free in the soil after a period of time.

Abstract

Provided is a green environment-friendly soil repairing agent (AZTR). The soil repairing agent (AZTR) is obtained through radical copolymerization of a monomer of polypropylene glycol ester, a vinyl unsaturated double bond-containing monomer, a fluorescent monomer which can achieve fluorescent tracing and unsaturated double bond-containing magnetic ferroferric oxide, and has a structural general formula represented as follows, wherein A is a copolymerized repeated structural unit of the vinyl unsaturated double bond-containing monomer, B is a copolymerized repeated structural unit of the fluorescent monomer containing unsaturated double bonds, C is the unsaturated double bond-containing magnetic ferroferric oxide, the polymerization degrees of x, y and z are 1-5,000, and the numbers, m andn, of the repeated units are 1-100. The soil repairing agent has good compatibility, can be used in combination with sepiolite, lime and other soil repairing agents, or can be used alone.

Description

technical field [0001] The invention relates to a soil remediation agent for planting Chinese herbal medicine and a preparation method thereof, which is a soil remediation agent suitable for planting Chinese herbal medicine and agricultural planting, and is especially suitable for remediation of soil with high heavy metal content. Background technique [0002] With the rapid development of urban industrialization, the "three wastes" discharged by various industrial and mining enterprises, as well as the burning of fossil fuels and the excessive use of chemical fertilizers and pesticides, heavy metals and chemical pollutants enter the soil through various channels, and the quantity and speed have far exceeded that of the soil. Capacity and purification speed. my country's current soil heavy metal pollution is very serious. The results of my country's multi-target regional geochemical survey conducted by the China Geological Survey show that 13% of the country's land area is p...
