Abstract As a necessary means of preventing and controlling diseases and insect pests, the widespread use of pesticides has brought great threat to the people’s health, so finding some more sensitive methods of pesticide residues is of great significance. Fluorescence spectrometry has the advantages of good selectivity, high sensitivity, quick sampling and less sampling. It can be used in the analysis and detection of pesticide residues. In this paper, Carbofuran of self-made standard pesticide solution concentration as test samples, acetonitrile as solvent were measured on samples by fluorescence spectrometer, 3D datas will be obtained by MATLAB to get the 3D fluorescence spectra. The experimental results show that using acetonitrile as solvent has little effect on the experiment and the intensity of the fluorescence spectrum has a good linear relationship with the concentration of carbofuran solution. The coefficient of correlation R2=0.997 4 and it is close to 1. So it is a feasible and reliable method to detect the carbofuran pesticide with the three-dimensional fluorescence spectrometry.
