摘要：

Using membrane ultrafiltration and size exclusion chromatography (SEC), the effect of Cd (II) and Cu (II) ions on the molecular weight distribution of humic acids (HA) in solution was investigated. It was shown that Cu (II) ions, unlike Cd (II), can take part in the formation of supramolecular HA associates (> 10 kDa).
