This standard specifies the method for the determination of dicofol residues in tea, fruit and edible vegetable oil. This standard is applicable to the determination of dicofol residues in tea, fruit and edible vegetable oil. The minimum detection amount of this method is 8.0×10-3ng. When the sample volume of fruit and tea leaves is 5.0g and the constant volume is 10mL, the minimum detection concentration of this method is 1.6×10-2mg/kg, and the lower limit of determination is 9.6×10-2mg/kg. kg. When the oil sample volume is 1.0g and the volume is 2mL, the minimum detection concentration of this method is 1.6×10-2mg/kg, and the lower limit of determination is 9.6×10-2mg/kg. The best linear range of this method: 8.0×10-3ng~1.0ng.
