摘要：

The assessment of conditional stability constants of aquatic humic substance (HS) metal complexes is overviewed with special emphasis on the application of ultrafiltration methods. Fundamentals and limitations of stability functions in the case of macromolecular and polydisperse metal-HS species in aquatic environments are critically discussed. The review summarizes the advantages and application of ultrafiltration for metal-HS complexation studies, discusses the comparibility and reliability of st;ability constants. The potential of ultrafiltration procedures for characterizing the lability of metal-HS species is also stressed. (C) 1999 Elsevier Science B.V. All rights reserved.
