Ryan, J L

The final separation and purification of Np from Pu, U, fission products, Th, and common metallic impuri-ties were investigated. It was found that Np(IV) can be absorbed on anion exchange resins from 6 M HNO/sub 3/ containing ferrous sulfanate and hydrazine. Procedure for eluting other metals from the resin are given as well as separation efficiencies. The choice of resin is listed along with elution techniques and a flowsheet. (J.R.D.)
