Copper complexation by naturally occurring organic matter: A multiligand model
Chemical Speciation And Bioavailability. Science & Technology Letters, v. 7, n. 4, n. 125, n. 131, 1995.
Extending the fluorescence quenching single-ligand model of Ryan-Weber, a multiligand model that does not require a direct measurement of the free metal ion concentration is proposed. It is shown that the problem of inconsistent negative ligand concentrations, commonly predicted by single-ligand models, may be overcome by using multiligand models. Finally, particular results concerning the conditional stability constants and ligand concentrations for one-, two and three- ligand cases are presented for soil fulvic acid, both before and after reverse phase HPLC fractionation.74125131
