| 中文摘要: |
| 综述了目前国内外土壤重（类）金属的消解方法及相关标准，分析了各种方法的优缺点。指出传统的电热板消解法已逐渐被淘汰，微波消解法应用广泛却存在一定的局限性，全自动石墨消解法自动化程度高，适合大批量样品前处理，应用前景良好。提出相对于加入氢氟酸的混酸消解法获得的土壤重（类）金属全量，王水消解法获得的土壤重（类）金属总环境有效态与生物有效性相关性更好，研究者可根据需要选择合适的消解方法。 |
| 英文摘要: |
| Domestic and abroad digestion methods and criteria of heavy metal(loid)s in soil were reviewed, and the respective advantages and disadvantages were summed up in this paper. It pointed out that the traditional electric plate digestion method was gradually eliminated. Microwave digestion method has been widely used, but there are some limitations. The automatic graphite digestion method has a high degree of automation and is suitable for great amount of sample pretreatment. Results showed that the total environmental available form of heavy metal by aqua regia digestion was better correlated with bioavailability than that by mixed acid digestion including hydrofluoric acid. Researchers can choose the appropriate digestion method to adapt to the needs of the study. |
