Pesticide Residual Detection

Application of Surface-Enhanced Raman Spectroscopy (SERS) for the Carbendazim in Astragalus
Pesticide residue 1.jpg

  • This study developed preliminary semi-quantitation methods for determine the carbendazim in astragalus using SERS (with 785 nm laser excitation).

  • For carbendazim, Raman shifts were observed at 624, 771, 1003, 1222, 1269, 1459, and 1514 cm-1.

  • The carbendazim residue in Astragalus was particularly identified at 771 and 1222 cm-1; the calibration curves could be developed by a linear equation (R2>0.97) or the Hill equation (R2>0.99).
