Heavy metal/food inspection parameter detection

Partial heavy metal detection methods:

(1) Common detection methods for lead in food include graphite furnace atomic absorption spectroscopy, with a detection limit of 5 micrograms/kg; Flame atomic absorption spectroscopy with a detection limit of 0.1 mg/kg; Single sweep polarography with a detection limit of 0.085 mg/kg; Dithizone spectrophotometry with a detection limit of 0.25 mg/kg; Hydride atomic fluorescence spectrometry with a detection limit of 5 micrograms/kg

(2) The commonly used detection methods for cadmium in food include graphite furnace atomic absorption spectrometry, with a detection limit of 0.1 micrograms/kg; Flame atomic absorption spectroscopy with a detection limit of 5 micrograms/kg; Photometric method with a detection limit of 50 micrograms/kg; Atomic fluorescence method with a detection limit of 1.2 micrograms/kg

(3) The commonly used detection methods for total mercury in food include atomic fluorescence spectrometry, with a detection limit of 0.15 micrograms/kg; Cold atomic absorption spectroscopy with a detection limit of 0.4 micrograms/kg (pressure digestion method) or 10 micrograms/kg (other digestion methods); The detection limit of dithizone spectrophotometry is 25 micrograms/kg. The analysis of methylmercury often starts with acid extraction and sulfhydryl cotton adsorption separation, followed by gas chromatography or cold atomic absorption spectroscopy for determination
