土壤中重金属含量分析前处理方法研究进展

Research Progress on Pretreatment Methods of Heavy Metals Analysis in Soil

综述了土壤中重金属含量分析前处理的方法,主要有酸溶消解法(包括电热板消解法、高压密闭消解法、微波消解法、全自动石墨消解法)、碱熔消解法和干灰化法等,对各种处理方法的优缺点进行了比较,并对重金属含量分析前处理方法研究方向进行了展望。

The pretreatment methods of heavy metals analysis in soil were reviewed in this paper, including acid digestion methods （electric plate method, high-pressure sealed vessels method, microwave digestion method and automatic graphite digestion method）, alkali fusion digestion method and dry ashing method, and the respective advantages and disadvantages of various methods were compared, while the development tendency of pretreatment methods of heavy metals analysis in soil was presented.
