研究了常用农药(大豆种衣剂、苄·二氯、吡虫啉、扑虱灵)水溶液的吸收光谱和荧光光谱，为农药残留检测提供依据。结果发现，农药在紫外区的吸收比可见区域强，不同种农药对应的最大吸收波长不同，吸收率也不同。扑虱灵吸收峰在227.5 nm、285 nm 处，吡虫啉吸收峰在210 nm、269.5 nm处，苄·二氯吸收峰在212 nm、238.5 nm、317 nm、331 nm 处，种衣剂吸收峰在226 nm、284.5 nm、330 nm、509 nm 处。这4种农药的水溶液均能够产生荧光，具有很强的荧光特性。扑虱灵的荧光峰在354 nm 和680 nm 处，吡虫啉的荧光峰在352 nm 和676 nm 处，苄·二氯的荧光峰在414 nm 处，种衣剂的荧光峰在352 nm 和675 nm 处。在相同激发条件下，不同农药的荧光光谱具有不同的强度和形状，可以通过对比光谱图定性判别农药的类别。

The absorption and fluorescence spectra of aqueous solution of several common pesticides (seed coating agent of soybean,benzal chloride,imidacloprid,and buprofezin) were studied,to provide an basis for detection of pesticide residue. The experimental results showed that the absorption rates of pesti-cides in the ultraviolet region were stronger than in visible light region,and the maximum absorption wave-length and the absorption rate of different pesticides were different. The absorption peaks of buprofezin lo-cated at 227. 5 nm and 285 nm. The absorption peaks of imidacloprid located at 210 nm and 269. 5 nm. The absorption peaks of benzal chloride located at 212,238. 5,317,331 nm. The absorption peaks of seed coating agent of soybean located at 226,284. 5,330,509 nm. Aqueous solutions of these four pesticides were able to produce fluorescence,and all of them had strong fluorescence characteristics. The fluores-cence peaks of buprofezin located at 354 nm and 680 nm. The fluorescence peaks of imidacloprid located at 352 nm and 676 nm. The fluorescence peak of benzal chloride located at 414 nm. The fluorescence peaks of seed coating agent of soybean located at 352 nm and 675 nm. Under the same excitation condi-tion,the fluorescence spectra of different pesticides had different strength and shape,so the category of pesticide could be distinguished by comparing the spectra.
