| 摘要: |
| 采用微波消解和ASD消解2种消解方式对不同土壤样品进行消解，ICP-MS测定其中重金属含量。微波和ASD2种消解方式均能够较好地提取土壤中的Cr、Co、Ni、Mn和V元素，实验结果的相对误差和相对标准偏差均≤10%，符合实验分析的要求。微波消解精密度优于ASD，可作为优先选择的前处理方法。 |

| Abstract: |
| Soil samples were digested by microwave digestion and automatic sample digestion (ASD) separately,and ICP-MS was used to determine heavy metals in the digestion solution.Both methods were shown well in extracting Cr，Co，Ni，Mn and V in soil,and the relative error and RSD were less than 10%,which were consistent with the requirements for laboratory analysis.The microwave digestion method was shown to have higher precision than the ASD method.Therefore,it was a preferred choice of pretreatment. |
