摘要：
A new model of solvent extraction of metal complexes with neutral ligands is presented. It was based on Bjerrum's concept of statistical effects in stability constants. This model required the minimum set of parameters describing a given extraction system. The usability of the model to evaluate the individual equilibrium constants related to both the aqueous and the organic phase was shown on the experimental example of nickel(II) nitrate complexes with N-propylimidazole ligands, extracted from water to dichloromethane.
