The excitation and emission wavelengths in the measurement are 345 nm, 430nm respectively. When the concentrations of FWAs are from 0 to 1.0 μg/mL, they have a linear relationship with the emitted fluorescence intensity. In this interval, the calibration curve is y=0.001 7x-0.018 7, and R2 is 0.999 2, the limits of detection and quantification are 4 μg/g and 10 μg/g respectively, and the average percentage of recovery is 95.3%, which meet the measuring requirements.

该方法激发波长为345 nm，发射波长为430 nm；定量标准曲线为y=0.001 7x-0.018 7，在0～1.0 μg/mL范围内线性相关性R2=0.999 2；方法检出限4 μg/g，定量限10μg/g，平均加标回收率为95.3%，可满足检测要求。

The average recoveries and coefficient variation of the methods were 90.19%~99.11% and 0.9%~3.2% for chlorothalonil, and 73.94%~86.47% and 2.6%~15.8% for thiram, respectively. The limit of detection for chlorothalonil and thiram were 1×10^(-12) g and 6×10^(-9) g, and the limit of quantification were 0.01 mg/kg and 0.3 mg/kg, respectively.

Methods: The protein and other impurity in the sample were precipitated by zinc acetate and potassium ferrocyanide after dipping of the sample. N,N-dichlorocyclohexylamine derived from sodium cyclamate by sodium hypochlorite in the filtrate was extracted by hexane. The HPLC separation was carried out with a phenomenex Gemini-C18 column using acetonitrile-water(7+3) or methanol-water (8+2) as mobile phase and detected by UV monitor at 314 nm. External standard method was used for quantification.
