摘要
用连续提取法研究地球环境中重金属的存在形态在土壤化学、植物营养和环境科学中均具有重要意义,很多研究者对之进行了广泛深入的研究。针对以前提取程序分级较多,不便于操作的特点,近些年来,一些研究者更注重于研究简便,应用性强,又能提供有价值信息的重金属形态区分方法。笔者对此方法研究的新进展及其应用作了综述,并对以后的研究进行了展望。
The application of sequential extraction procedure to research of the fractionation of heavy metals in geochemical environment has important significance in soil chemistry, plant nutrition and environmental science. Many scientists researched deeply and developed almost ten schemes. But there are too much fractionations be distributed and they are inconvenient for operation in the previous schemes. In recent years, scientists strive to research simpler and more practical extraction schemes. This paper reviews the sequential extraction procedure for metals, including its progress and application in practice, and makes the prospect for the future research.
