农药残留检测仪的设计与实现

Design and Implementation of Pesticide Residues Detector

针对农药在蔬菜中的大量使用,造成蔬菜在食用时难免会有农药的残留,危及人们的健康及生命安全的情况。设计了农药残留检测仪。通过农药对酶的抑制,测出农药对酶抑制前后吸光度的变化,从而测出农药对酶的抑制率,不同的抑制率代表蔬菜所含农药浓度不同,从而便可检测出农药是否超出设定标准。

In recent years ,large scale use of pesticides in vegetables has inevitably resulted in pesti‐cide residues ,which could endanger people’s health and life .The core task of the design is to detect pesti‐cide residues in vegetables .Based on the role of pesticides in inhibiting the enzyme ,the changes in absor‐bance before and after the inhibitory effect of pesticides on enzyme are measured .Then the rate of inhibi‐tion of pesticides on enzyme is measured .Different inhibition rates represent different concentrations of pesticides the vegetables contain .This method can detect whether a pesticide is beyond the set standard .
