Description

Extraction '84 presents the proceedings of the Symposium on Liquid–Liquid Extraction Science, held in Dounreay, Scotland, on November 27–29, 1984. This book discusses the principle involved in liquid–liquid extraction. Organized into 22 chapters, this compilation of papers begins with an overview of the performances of pulsed columns, including decontamination factors and recovery yields. This text then discusses the alternative ways of managing neptunium in the Purex process and reviews the main coordination and redox characteristics of neptunium in nitric medium. Other chapters consider the mass transfer measurements made in a pulsed plate liquid–liquid extraction column. This book discusses as well the extraction of uranium from wet process phosphoric acid. The final chapter deals with full-scale pulse column tests, which have been performed with uranium and simulated fission products to evaluate. This book is a valuable resource for chemical engineers, chemists, chemical physicists, and research workers.
