摘要: Residual pesticides in agricultural production are one of the major food safety concerns around world. In this study, we investigated amount isofenphos-methyl corns by using surface-enhanced Raman spectroscopy (SERS) coupled with chemometric methods. The highest peak at 1043 cm−1 was used to detect and quantify spiked methanol-water (1:1) solvent corns. limits detection (LODs) were 0.01 μg/mL 0.01 μg/g, respectively. Quantitative residues (0–5 μg/mL) conducted partial least squares (PLS) model. Based upon results leave-one-out cross-validation, could be predicted PLS (the correlation coefficient 0.9964) a low root mean square error calibration (RMSEC=0.146). developed SERS method provides much simpler more sensitive way monitor for safe corns, which can extended other products.
