Liquid-liquid extraction or solvent extraction is the separation of the components of a liquid solution by contact with another liquid solvent, which is relatively immiscible with feed solution. The liquid, which is added to the solution to bring out extraction, is known as solvent. This solvent takes up part of the solute and forms an immiscible layer with the remaining solution. The solvent layer is called extract and the other layer is called raffinate.

Liquid-liquid extraction or solvent extraction is the separation of the components of a liquid solution by contact with another liquid solvent, which is relatively immiscible with feed solution. The liquid, which is added to the solution to bring out extraction, is known as solvent. This solvent takes up part of the solute and forms an immiscible layer with the remaining solution. The solvent layer is called extract and the other layer is called raffinate. Extraction involves the use of systems composed of at least three substances and although for the most part of the insoluble phases are chemically very different, generally three components appear at least to some extent in both phases. In this work analysis of batch extraction for different concentrations of solute and solvent with respect to time is done. It is found that % recovery of solute increases with increasing the concentration of solute and decreases with increase in the quantity of solvent. This work is aimed for utilization by researchers, industrialists¿ and traditional businesses. Apart from this it will be especially relevant and useful for the students of Chemical & Process Engineering for carrying out research.
