Solvent Extraction and Ion Exchange - tandfonline

ABSTRACT The solvent extraction of alkali and alkaline earth metals (Li, Na, K, Mg, Ca) was studied using organophosphorus compounds like di-2-ethylhexylphosphoric acid(D2EHPA) or 2-ethylhexyl-phosphonic acid 2-ethylhexyl ester (MEHPA) as extractants. Extraction equilibrium constants and composition of each metal complex in organic phase were determined.

Practical Aspects of Solvent Extraction | LCGC

Table I provides examples of typical extraction solvents, as well as some unsuitable (water-miscible) extraction solvents. Apart from miscibility considerations, the main selection criteria is the polarity P' of the solvent in relation to that of the analyte.Maximum K D occurs when the polarity of the extraction solvent matches that of the analyte. . For example, the extraction of a polar ...

Liquid–liquid extraction - Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Soxhlet extractor - Wikipedia

A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently ...
