Abstract：In the present paper the basic theory that an organic substance can emit fluorescence as it is excited by ultraviolet rays is described and the relationships between the molecular structures of organic substances and fluorescence generation are studied. According to this theory, the molecular structures of a few common carbamate pesticides such as carbaryl, carbofuran and propoxur etc. are analyzed, their fluorescence characteristics are shown, and the mechanism of fluorescence generation of carbamate pesticides is ascertained. It provides a theoretic basis for further detecting carbamate pesticides by means of a fluorescence analytical method. Moreover a steady-state fluorescence spectrograph is applied to conduct fluorescence spectrum experiments with standard carbaryl solution and carbofuran solution. The results indicate that carbamate pesticides may emit fluorescence as excited by UV under the condition of a certain solvent, and that their fluorescence spectra are distinct and have fine resolution and less interference. It is feasible to detect carbamate pesticides by fluorescence spectral analysis.
