STUDIES ON EXTRACTION OF SOME METALS WITH CARBOXYLIC ACIDS

Abstract

Solvent extraction is rated as one of the most potential separation techniques mainly because of its versatility, speed and ease of operation. The technique can be safely extended from tracer level to macro concentration. It has an extremely wide range of application and invokes most of the physloal and chemical principles used generally In analytical chemistry. Liquid-liquid extraction can be used for the purposes of preparation, purification, enrichment, separation and analysis. The extraction processes have proved to be of Immense Importance in the study of kinetic as well as thermodynamic aspects of chemical reactions, notably metal complex formation, both In aqueous and non aqueous phases. While the new analytical extraction procedure may be developed using familiar reagents, the testing of new reagents may be achieved with considerable ease* Solvent extraction chemistry has provided a rational, useful guide to the design of many new chromatographic procedures, particularly those Involving 'reversed phase' techniques. The application of the extraction prooess in the field of nuclear fuel processing and transplutonium chemistry deserves a special mention..................
