| 中文摘要: |
| 本文采用电感耦合等离子体发射光谱法(ICP-AES)轴向和径向测定土壤中铜、锰、钒、锌四种金属元素的含量，比较分析了在不同三酸[硝酸(HNO3)、氢氟酸(HF)、高氯酸(HCLO4)]用量(配比)下对5种国家标准物质的消解性差异和对四种元素轴向和径向测定结果的影响。结果表明:(1)消解过程中f、g、h配比的三酸消解速度较快，d、e次之，a、b、c相对较慢。(2)对于低含量试样径向观测对轴向观测灵敏度较高；同时三酸消解用量不同，其结果差异性不明显，而发现中高含量范围内横向观测比径向观测相对偏差较小，说明了轴向观测效果较好。(3)通过采用f配比的三酸经过前处理进行稳定性分析，结果可知标准偏差(SD)均小于10，相对标准偏差(RSD)均小于5%，对于高含量锰元素横向观测较径向观测稳定性高，其余元素差异性不明显。 |
| 英文摘要: |
| The amounts of Cu, Mn, V, Zn in the soil were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) axial and radial, then analyzed the digestion difference of 5 standard substances with different amount acids [(HNO3)、(HF)、(HCLO4)] and the influence of four elements on the results of the determination axial and radial . The result showed that: (1)when the ratio of three acid is f, g and h, the digestion is the fastest, then is d and e, the ratio of three acid is a, b and c is the lowest. (2) For low concentration samples, radial observation sensitivity is higher than the axial observation; the difference of the result is not obvious with different amount acids, but the relative deviation of axial observation is less than radial observation, and this indication that axial observation work well for the high content of samples.(3) Pretreatment for stability analysis use three acid of f ratio, the standard deviation (SD) of the results are all less than 10, the relative standard deviation (RSD) of the results are all less than 5%. For high elements(Mn)of concentration samples, the stability of the result through axial observation is better than radial observation, and the difference in the rest of the results is not obvious. |
