摘要： The method of near-infrared attenuated total reflectance infrared and Raman spectroscopy was used for the rapid determination of the content of deltamethrin in agrochemicals The quantitative models were established by PLS (partial least squares) method and optimized. The Independent validation sets were used to evaluate the model accuracy The determination coefficient R(2) and RMSECV of the near-infrared model and mid infrared model were 0 999 9, 0 022 and 0 999 6 and 0 056 respectively The accuracy of both was similar The determination coefficient R(2) and RMSECV of Raman were 0 996 7 and 0 172 which exhibits the lower accuracy The result indicated that near-infrared mid-infrared and Raman spectroscopy can be applied to the rapid determination of the content of the active ingredients precisely which has an important significance in the on line de termination analysis on site in the enterprise and the rapid quantitative analysis of agrichemicals in the department of quality monitoring
