Study on Rapid Detection System of Pesticide Residue Based on Photoelectric Method

Pesticide residues are unwanted chemical substances left after pesticides are applied to plants. Insecticides can be sprayed on crops or used as liquid sprays, but some of these chemicals may eventually enter the ground and water systems, which may cause health problems for many animals, such as humans and other animals. Based on the modification and improvement of the classical photoelectric method, a mobile photoelectric. The method is based on a set of parameters that determine the amount of light absorbed by any sample. When the spectrophotometer is used to measure the amount of light emitted by any sample according to certain wavebands, the absorption spectrum can be found.
