| 中文摘要: |
| 土壤重金属有效态含量作为评价土壤污染程度的指标越来越被认可，为了更好地研究土壤中重金属有效态的分析测试方法，本文综述了近年来土壤中重金属有效态分析技术研究进展。重点阐述了单步提取法、连续提取法，对单步提取法中中性盐、络合剂、酸溶液三类提取剂、电感耦合等离子体等仪器分析方法进行综述。建立有效、准确的土壤中重金属有效态的测试方法，以及标准物质等方面的研究，将为土壤污染风险评估及土壤污染修复工作起到指导作用。 |
| 英文摘要: |
| The content of available heavy metals in soil is recognized as an index to evaluate the degree of soil pollution. In order to study the analysis and testing methods of available heavy metals in soil，this paper reviews the research progress of available heavy metals analysis technology in soil in recent years. The review including various pretreatment methods such as single-step extraction method and continuous extraction method. This paper focuses on three kinds of single-step extraction agents, including neutral salt,complexing agent and acid solution.It also reviews analytical methods such as inductively coupled plasma mass spectrometry and other methods. The establishment of effective and accurate testing methods for the determination of available heavy metals in soil and the research on standard substances will play a guiding role in soil pollution risk assessment and soil pollution remediation. |
