王水消解-原子荧光光谱法测定辣木茶中的汞、砷和硒
Determination of mercury, arsenic and selenium in Moringa tea by atomic fluorescencespectrometry method with the samples dissolved in aqua regia
摘要
Abstract
Mercury, arsenic and selenium in Moringa tea were determined by atomic fluorescence spectrometry method with the samples dissolved in aqua regia.The results show that: The mercury and arsenic residue in Moringa tea were 0.0144 and 0.3270 mg/kg respectively, which conformed to the national quality safety requirements of heavy metal residue in tea.The selenium content in Moringa tea was 0.1350 mg/kg, which belonged to the selenium-rich food compared with tea.The method of mercury, arsenic and selenium determination in Moringa tea by atomic fluorescence spectrometry with the samples dissolved in aqua regia was a kind of feasible methods of heavy metal element in food which showed advantages of high precision, good accuracy, high sensitivity, less interference, and simple operation.关键词
