| 摘 要： | 采用高压消化罐在较低温度下进行缓慢样品消化,减少了消化过程中微量元素的损失.用电感耦合等离子体原子发射光谱法测定了野生元蘑和珍珠菇中钙、钠、钾、镁、锰、钡、铁、钴、锗、铜等微量元素的含量,并比较了湿法消化的结果,两种方法无显著性差异.方法的相对标准偏差在0.28%～2.96%之间,回收率在96.4%～104.0%之间.

| Abstract: | The mushroom sample was digested in a closed teflon vessel placed in heating oven to avoid loss of analytes, and trace elements Ca, Na, K, Mg, Mn, Ba, Fe, Co, Ge, Cu in the prepared solution were then determined by ICP spectrometry. Comparison of the results obtained by the present method with those by the routine wet digestion showed that no significant difference was found between the two methods. RSDs of the method were in range of 0.28%-2. 96% and recoveries were ranged in 96. 4%-104. 0%. |
