Anion-Exchange Recovery of Thorium from Uranium: Analytical and Preparation Aspects

Radiochemistry, 2003
Recovery of thorium from U(VI) containing 20% 235U in 7 M HCl with AV-17-8 chs anionexchanger [GOST (State Standard) 20301-74] was studied using a Ge-Li detector. An 1 cm column in diam-eter with 40-cm resin bed height ensures complete thorium separation from 1 g of U sorbed on the resin.
