Solvent extraction is a common technique utilized for both industrial applications and in the laboratory. The technique is successfully applied as a sample preparation procedure for chromatography. It can be used for separation purposes by using selective extractions, or for concentration purposes.

Solvent extraction of hafnium [PDF]
Proceedings / Indian Academy of Sciences, 1978 Mixed chelates of hafnium in benzene medium was studied by the method of solvent extraction. Various β-diketones and their mixtures were used for the study. The equilibrium constants for the mixed complexes were evaluated. Synergism in the extraction of hafnium in the presence of two dissimilar acidic extractants viz.

Introduction to Solvent Extraction
2004The term solvent extraction† refers to the distribution of a solute between two immiscible liquid phases in contact with each other, i.e., a two-phase distribution of a solute. It can be described as a technique, resting on a strong scientific foundation.

Publisher Summary This chapter describes solvent extraction or liquid–liquid extraction as a partitioning process where a solute distributes itself between two immiscible phases. The basic process is the same as in partition chromatography; the difference lies in the experimental technique of performing the operation in the laboratory.

THERMODYNAMICS OF SOLVENT EXTRACTION
Solvent Extraction and Ion Exchange, 2000ABSTRACT The fundamental thermodynamic characteristics of aqueous electrolyte solutions and organic solutions which affect solvent extraction are summarized and the influence of metal complexation and hydration on the distribution ratios is discussed. The thermodynamics of extraction systems, including synergistic systems, is reviewed. The influence of

THE separation and determination of small amounts of indium in the presence of other metals, especially beryllium and iron, are analytical problems of importance for which no entirely satisfactory solution has as yet been published. Mathers and Prichard1 precipitated iron as its cupferrate; but some 4 per cent of indium is co-precipitated.
