Abstract

The invention relates to a method for photocatalytic degradation of pesticide residues. The method is characterized by: taking butyl titanate, zinc acetate, urea and the like as raw materials, conducting co-precipitation to synthesize a ZnO / TiO2 composite nano-material with photocatalytic activity, spraying the composite nano-material on plants, and making use of sunlight irradiation to degrade pesticide residues. The material has high absorption strength and strong photocatalytic activity in both ultraviolet and visible ranges, and has the characteristics of obvious degradation effects, simple operation and low cost when used in pesticide residue degradation, thus having wide application and popularization value.

Description

technical field

[0001] The invention relates to a method for degrading and removing pesticide residues, in particular to a method for photocatalytically degrading pesticide residues. Background technique

[0002] Pesticides play an extremely important role in the production and preservation of agriculture and animal husbandry, as well as the prevention and control of infectious diseases. However, the residual pesticides will also have a negative impact on human health. If they accumulate in the human body to a certain dose, they will cause acute or chronic poisoning to the human body, and even produce highly carcinogenic, teratogenic, and mutagenic effects. At present, some developed countries have established regulations on the maximum limit of pesticide residues, which have become an invisible technical barrier. It can be seen that controlling and reducing pesticide residues is necessary both from the perspective of being responsible to consumers and from the perspective ...
