This paper discusses the kinetics of solvent extraction, which is influenced by the chemical reactions occurring in the system and the rates of diffusion of various species. The objective is to explain the dependence of kinetics on these chemical reactions, exemplified through the extraction of metal cations from aqueous solutions using chelating extractants in organic solvents. The methodology involves analyzing how different factors affect the extraction process, including the role of solvation and the formation of new coordination compounds. Furthermore, the research highlights complications in solvent extraction systems, such as reactions occurring in two bulk phases and at the liquid-liquid interface. Key principles, including Fick's laws of diffusion, are examined to provide a simplified view of the diffusional processes associated with the extraction. The findings suggest that when chemical steps are slower than diffusion rates, the kinetics of extraction will align with the rate of these slow reactions. Overall, this work emphasizes the complex interplay between chemical reactions and diffusion in solvent extraction kinetics.
