| Abstract: | A rapid and sensitive method to identify and analyze mixed pesticides of tricyclazole, paraquat and flusilazole by surface-enhanced Raman scattering has been reported. Aqueous samples can be detected by SERS in low concentrations of 0.01 mg/L, 0.1 mg/L and 2.85 mg/L for individual tricyclazole, paraquat and flusilazole respectively. When mixing the three pesticides in the low concentrations, their characteristic peaks can still be identified from the SERS spectrum of the mixture. |
