Abstract:In order to offer the quick analysis of concentration of pesticides residues in agricultural products, a mixed procymidone-honey system was built and studied according to the principle of fluorescence spectrum. The relationship between the fluorescence intensity and the procymidone content in honey was also analyzed. With the aid of steady fluorescence spectrometer, the fluorescence spectra of procymidone solution and honey solution were detected respectively. The fluorescence emission peaks of pure honey and procymidone are found at about 342 nm and 390 nm. The fluorescence peak position has a red shift (from 342 nm to 390 nm) with respect to an addition of procymidone (0.1 g/dL) into honey, indicating the interaction between procymindone and some substances in honey. By using software program of Origin8.5 which is used to process and analyze data, the linear fitting is done of the fluorescence peak intensity of the honey and the content of procymindone. The results show that the prediction models between the fluorescence intensity and procymidone content in honey has a good linear relationship. The function model is I=188504.75x+384764.33, and the correlation coefficient is 0.99. The experimental results under the same conditions show that the accuracy of the function model is 96.8%-100%. The results can be concluded that the determination of procymidone is effective and reliable for the concentration testing of procymidone residues in other agricultural products. © 2017, Science Press.
