用干法和湿法消解大豆样品，并用火焰原子吸收分光光度法测定了其中Ｃｕ，Ｍｎ，Ｐｂ，Ｎｉ，Ｃｄ的含量，比较了两种消解方法的测试结果．结果表明，干法消解与湿法消解在精密度方面有显著差异．干法消解样品时，测得的结果重现性好；湿法消解更适合大批量样品的处理．关键词 Soybean samples were digested by both dry and wet methods, and the contents of Cu, Mn, Pb, Ni and Cd were determined by flame atomic absorption spectrophotometry. The results of two digestion methods were compared. The results show that there are significant differences in the precision between dry digestion and wet digestion. Dry digestion samples, the measured results reproducibility; wet digestion is more suitable for processing large quantities of samples. Key words
