A comprehensive review of the sequential extraction schemes for metal fractionation in environmental samples (ie., sediment, soil, sewage sludge, fly ash, etc.) is presented. The review contains more than 400 references and covers principally the literature published over the last decade. The use of each reagent involved in these schemes is looked at critically, and guidelines for their selectivity and extraction capacity are given. The operational character of these schemes is emphasised. Topics such as comparability between sequential extraction schemes of widespread use, harmonisation, acceleration, validation, etc. are addressed and future developments outlined.
本文对环境样品（即沉积物、土壤、污水污泥、粉煤灰等）中金属分级的连续萃取方案进行了全面综述。该综述包含400多篇参考文献，主要涵盖了过去十年发表的文献。对这些方案中涉及的每种试剂的使用进行了批判性审视，并给出了其选择性和萃取能力的指导原则。强调了这些方案的操作特性。讨论了广泛使用的连续萃取方案之间的可比性、协调、加速、验证等主题，并概述了未来的发展方向。
