This book was released on 1965 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rapid procedure was devised for the quantitative recovery of the individual rare earth elements and yttrium from a synthetic mixture of carrier-free yttrium, terbium, europium, samarium, promethium, neodymium, praseodymium, cerium and lanthanum radionuclides. The separations are accomplished in 14 hours by elution from a Dowex 50W-X4 resin column with alpha-hydroxyisobutyrate solutions at room temperature. (Author).
