Discussion on analytical method of chlorate and perchlorate in food

Perchlorate is a new type of environmental pollutant with high diffusivity and durability. It can interfere with the normal function of the human thyroid gland and affect human growth and development. The determination of chlorate and perchlorate in food is of great significance for ensuring human health, and it is also a hot issue in international and domestic research. At present, there are various analytical methods at home and abroad to achieve quantitative detection of chlorate and perchlorate, including ion chromatography, ion chromatography- mass spectrometry, liquid chromatography-mass spectrometry. This paper reviewed the research status of chlorate and perchlorate analysis and detection methods in foods in recent years, discussed the principles, application status and relevant standards of various analytical techniques, compared their advantages and disadvantages and put forward the prospects.
