摘 要: 选用了中国宁夏中宁早康枸杞园林场生产的枸杞、山东省沾化金丝枣、山西柳林县红枣,用火焰原子吸收分光光度法和石器炉法剐这三种样品中的金属元素Fe、Cu、zn、Mn、Ca、Pb的含撮进行了测定。测定方法简单,精密度和灵敏度高,回收率为105.1%-93.1%。结果可靠。 The content of metal elements Fe, Cu, Zn, Mn, Ca, Pb of the Jujube collected fiom Ningxia of China and Lycium barbarum collected from two different places Shandong Zhanhua and Shanxi Liulin were determiened by flame atomic absorption spectrometry and graphite furnace atomic absorption spectroscopy. It is satisfying by simple method , high precision and the recovery ratios in the range of 99.34% - 105.40%.
