PESTICIDE DEGRADATION METHOD BASED ON LED PULSED LIGHT

摘要

Disclosed is a pesticide degradation method based on LED pulsed light, comprising using a spectrum controller to regulate the wavelength of the excitation light of an LED light-emitting body and to control the flash frequency of the LED light-emitting body. The arrangement of the spectrum and the rational irradiation period can largely degrade residual pesticides retained in vegetables and fruits. Experiments demonstrate that under the action of LED pulsed light, the residual content of residual pesticides in vegetables and fruits effectively decreases through photocatalytic decomposition. In addition, using ultraviolet light UV-A at a wave band of 350 nm-400 nm can increase the nutrients in vegetables and fruits and improve the colour and taste thereof.
