摘　　要：采用火焰原子吸收光谱法测定番石榴中K、Na、Mg、Ca、Fe、Zn、Cu、Mn等八种微量元素,方法的相对标准偏差在0.65%-2.3%之间,回收率在97.6%-103%之间,分析结果表明番石榴中含有丰富的金属元素,该法简便、灵敏度高、结果准确。The trace elements of K, Na, Mg, Ca, Fe, Zn, Cu, Mn in guava are determined by using flame atomic absorption spectrophotometry. The relative standard deviations（RSDs） of the methods are within 0.65% - 2.3% and the recoveries obtained are in the range from 97.6% to 103%. As a result,it has been proved that the trace metal elements are abundant in guava. The method is convenient, rapid and accurate.
