紫外线降解水果中农药残留设备的设计与试验
Design and application of ultraviolet degradation equipment for pesticide residue in fruits
摘要
Abstract
In order to explore the effective methods for degradation pesticide residue contained in fruits, an equipment for degredation of pesticide residue in fruits was developed by means of ultraviolet rays irradiating.The degradation effects of pesticide residues contained in Jonagold apple and Dangshan pear was studied with the equipment.Using ultraviolet of 253.7 nm wavelength and 2 243 μW/cm2 effectual intensity to treat the apple and pear with dichlorovos,fenvalerates for 3, 2, 1 and 0.5 min separately.compared with untreated samples (taken as reference,CK), the results indicated that the pesticide residue of the treated fruits was reduced obviously.The results show that the treatment with 1 min has the best comprehensive effect which degradation rates of Dimethoate residue in the apple and pear are 57.40％ and 60.12％, the degradation rates of fenvalerates are 42.23％ and 41.25％.At the same time the pesticide residues in fruits are far below national standard.关键词
