摘　　要：针对国内主要食品中广泛存在的农药残留带来的食品安全问题,研究一种方便快捷且成本适宜的检测技术,具有重要的意义。目前,已有相关实验将光谱吸收技术用于食品农药残留检测,但是,对于定量检测及测量精度方面该实验还存在一些不足。本文基于差分吸收技术,采用荷兰Avantes公司的微型光纤光谱仪以及分光光度计,进行了相关实验,实现了对敌敌畏水剂农药的定量测量,从而对基于光谱吸收技术的农药残留检测技术进行了完善,使其更加适合实际应用。For the domestic food safety problem that caused by the pesticide residues in food,it＇s very important that research a convenient and cost-appropriate detection technology.At present,spectroscopy absorption technology has been used for detection of pesticide residues in food.However,there are some deficiencies such as the quantitative detection and the measurement precision.This experiment that based on differential absorption is completed by using miniature fiber optic spectrometer and spectrophotometer,and then the pesticide dichlorvos is also measured quantitatively.Thus the pesticide residue detection technology that based on spectroscopy absorption is improved to adjust to the practical application.
