STUDY ON PHOTOCATALYTIC DEGRADATION OF PESTICIDE RESIDUES IN FOOD
ABSTRACT
In this paper, the application and development trend of photocatalytic degradation technology in the treatment of pesticide residues in food were discussed comprehensively and deeply. In view of the increasing importance of food safety in the world, pesticide residues have become one of the key issues to be solved in the field of food safety. Photocatalytic degradation technology, with its high efficiency, green, sustainable and other significant advantages, provides an innovative and promising solution for pesticide residue treatment. In this paper, the core principle of photocatalytic degradation technology is described in detail, including how the photocatalyst absorbs light energy and converts it into chemical energy to drive the oxidative decomposition process of pesticide molecules. Then, the types and unique characteristics of various photocatalysts are systematically introduced, and the key factors affecting the efficiency of photocatalytic reaction are analyzed, such as the type of light source, the amount of catalyst, the reaction medium, etc. In the application of pesticide residue treatment, this paper focuses on the photocatalytic degradation of a variety of common pesticides, and emphasizes its significant advantages of no secondary pollution and environmental friendliness in the treatment process. In addition, this paper also discusses how to adapt photocatalytic degradation technology to different processing scenarios, including food processing, storage and transportation, and shows its wide application prospects. In order to further improve the treatment effect of photocatalytic degradation technology, this paper also proposed a number of optimization and improvement measures, including the modification of catalyst, optimization of reaction conditions, and integration of interdisciplinary technologies.
