| 中文摘要: |
| 采用干法灰化和微波消解两种样品分解方法处理植物试样，用电感耦合等离子体发射光谱法测定样品中铝、钡、钙、铜、钾、镁、钠、铁等22个主、次量元素的含量，用两种前处理方法对国家一级标准物质进行测定，比对测定值与标准值，验证两种方法的准确度和精密度。结果表明，不同的样品分解方法对各元素的测定结果会产生不同程度的影响。选择适宜的分解方法可以大大提高植物样品中铝、铁、硫等元素测定结果的准确度。干法灰化和微波消解两种前处理方法的精密度（RSD，n＝11）均小于5％。 |
| 英文摘要: |
| Plant samples were decomposed by two different methods of microwave digestion and dry ashing. 22 elementssuch as Al，Ba，Ca， Cu， K，Mg，Na，Fe，etc were determined by inductively coupled plasma-atomic emission spectrometry. National standard reference materials were also measured along with the plant samples to test the accuracy and precision of the two methods. The experimental results indicated that different decomposition methods influenced measurement results in various degrees and adequate selection of decomposition methods can improve the accuracy of measurement results of Al，Fe，S，etc in plant samples. The precision of two methods was better than 5%RSD (n=11). |
