摘要
研究了采用微波消解样品,利用火焰原子吸收分光光度法(FAAS)测定了大鼠肝脏中的钙、锌、铜、镁、铁.考察了微波消解条件对分析结果的影响,同时选择了火焰原子吸收分光光度法测定的最佳条件.实验结果表明,与传统的湿法消解样品相比,该方法操作简便、快速、样品消解完全,空白值低,选择性好,准确度和精确度都能满足分析要求.利用该法对大鼠肝脏中的微量元素进行了分析,测定结果令人满意.方法回收率在96%～103%,相对标准偏差为1.0%～2.6%.
In the present paper, microwave digestion technique was used to determine Ca, Zn, Cu, Mg and Fe in rat liver by flame atomic absorption spectrometry （FAAS）. The effect of microwave digestion condition on the analysis results was examined and the best analysis condition of FAAS was selected. Compared to traditional wet methods, the experimental result showed that the method is rapid, sample digestion is complete, the blank value is low, and the measurement result is satisfactory. Applied to the determination of trace elements in rat liver, the method proved to be selective with satisfactory recovery of 96%-103% and relative standard deviation of 1.0%-2.6%.
