Abstract

The invention provides a high polymer compound chelated with heavy metal elements, which is characterized in that the compound comprising a functional group that can provide lone pair electrons is loaded on a high polymer vector and the heavy metal elements are chelated on the compound. The invention also provides a preparation method of the high polymer compound and application thereof to removing pesticide residues. The invention has the advantages that: the high polymer compound has easily-obtained raw materials, lower cost as well as simple preparation method and use method, can simultaneously remove a plurality of pesticide residues efficiently, rapidly and conveniently and reach national standards related to pesticide residues; and the invention has no defects in a biodegradation method, a physical removing method and a chemical degradation method, and the like which are used commonly and is a good method which can be popularized and has industrial potential.

Description

technical field [0001] The invention relates to the technical field of polymer complexes, in particular to a polymer complex chelated with heavy metal elements. Background technique [0002] Pesticides are important means of production to ensure high yields in industries such as agriculture, forestry and animal husbandry. The large-scale promotion and use of pesticides has ensured the continuous increase in the output of agricultural, forestry and animal husbandry products, and has become an important means of improving human food supply; secondly, pesticides are also used to kill and control mosquitoes that endanger human and animal hygiene and health. , flies, lice, fleas and cockroaches and other pests and germs, so that people and animals can live peacefully and stably, and grow up healthily. Therefore, the importance of pesticides to the modernization of a country is self-evident. [0003] However, the pesticide residues caused by the use of pesticides have brought se...
