摘要

An optical instrument was developed to determine the pesticide residues in vegetables based on the inhibition rate of organophosphates against acrtyl-cholinesterase (AChE). The instrument consists mainly of a solid light source with 410nm wavelength, a sampling container to store the liquid, an optical sensor to test the intensity of transmission light, a temperature sensor, and a MCU based data acquisition board. The light illuminates the liquid in the sampling container, and the absorptivity was determined by the amount of the pesticide residues in the liquid. This paper involves the design of optical testing system, the data acquisition and calibration of the optical sensor, the design of microcontroller-based electrical board. Tests show that the absorption rate is related to the pesticide residues and it can be concluded that the pesticide residues exceed the normal level when the inhibition rate is over 50 percent.
