摘　　要：随着我国工业化进程的加快,土壤重金属污染问题日益加剧。为有效开展土壤重金属检测工作,提高数据的准确性,本文对几种前处理技术进行了研究。通过测定土壤重金属成分标准物质的回收率和标准偏差,分析微波消解法、高压罐消解法、电热板法和王水水浴消解法各自的应用优点。实验证明,不同的消解方法产生的结果存在一定差异,不同重金属元素采用不同消解方法所测得的标准物质存在一定标准偏差,与样品前处理技术密切相关。由于每种前处理技术都有其自身优点,在实践中应充分考虑到前处理技术的便捷性、准确性、稳定性等因素,合理选择。With the acceleration of industrialization in China,the problem of heavy metal pollution in soil is increasingly intensifying.In order to effectively carry out soil heavy metal detection and improve the accuracy of data,several pretreatment techniques are studied.By determining the recovery rate and standard deviation of soil heavy metal composition reference materials,the application advantages of microwave digestion,high-pressure tank digestion,electric hot plate method and aqua regia bath digestion method were analyzed.Experiments show that there are certain differences in the results produced by different digestion methods,and there is a certain standard deviation of the standard materials measured by different heavy metal elements using different digestion methods,which is closely related to the sample preparation technology.Each pretreatment technology has its own advantages,and in practice,the convenience,accuracy,stability and other factors of the pretreatment technology should be fully considered,and the reasonable choice should be made.
