| Abstract: | 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. |
