Methods: Samples were sealed with nitric acid under high pressure and the content of boron was determined by inductively coupled plasma spectrometry. Results: The method showed a good linearity in the range of 0 mg / L ~ 10 mg / L with a linearity coefficient of 0.99999. The detection limit was 0.44 mg / kg. The relative standard deviations of 6 determinations were less than 4% Analysis results in the certificate value range. Conclusion: The method is sensitive and accurate with wide linear range and is suitable for the determination of boron in food.
