Available in PDF, EPUB and Kindle. Book excerpt: It was demonstrated that neptunium(IV) can be readily absorbed onto anion exchange resins from 6 M HNOsub 3/ containing ferrous sulfamate and hydrazine or semicarbazide, separated from plutonium, uranium, and common metallic impurities by washing the resin at 25 deg C with 6 M HNO/sub 3/ containing ferrous sulfamate and hydrazine or semicarbazide, separated from fission products and thorium by washing the resin at 60 deg C with S M HNO/sub 3/- 0.01 M HF containing hydrazine or semicarbazide, and eluted at concentrations greater than 40 g Np/l with 0.35 M HNO/sub 3/ at 25 deg C. Decontamination factors of greater than 10,000 from uranium, plutonium, and common metallic contammants, greater than 25,000 for fission products normally expected in the feed (mainly Zr-Nb with some Ru-Rh), and greater than 1000 for thoriuin are obtainable under proper operating conditions. Because of the low processing rates, the necessity for carrying out the absorption cycle at 25 deg C and the absence of radiation daraage problems, Dowex 1, X-4 (50-100 mesh) or Dowex 21K (50-100 mesh) resins are considered the best choices for this application. Gassing occurs with the use of ferrous sulfamate - semicarbazide reductant but is not a serious problem and does not occur with ferrous sulfamate -hydrazine reductant in 6 M HNO/sub 3/. (auth).

Book excerpt: Nine papers are included which were presented at the meeting in Oak Ridge. The papers are chiefly on plutonium separation by anion and cation exchange, although ion exchange contactors, amine extraction of plutonium, and uranium recovery from reduction residues are briefly treated. Separate abstracts have been prepared for each paper. (D.L.C.).

This book was released on 1964 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anion exchange adsorption from a nitric acid medium has many specific uses and much has been published about the characteristic behavior of various metallic ions in such media. To gain more complete information of the Analytical Group of the Chemistry Division at Argonne made a series of studies in which the adsorption of most metal ions from nitric acid solutions. This work has now been extended to include the behavior of some 70 elements in acid concentrations ranging down from 0.1M. Both column elution and batchwise techniques were used in the experiments, as well as radiochemical, chemical, and optical emission spectrographic methods of analysis.
