Everest, D A; Wells, R A; Sims, G H.E.

An anion-exchange material suitable for uranium recovery may be prepared by aminating polyvinyl chloride sheets with NH/sub 3/ or an amine to the extent that at least l% of the combined chlorine atoms is replaced with basic nitrogen- containing groups. if a polyamine, e.g., a diamine, is used for the amination, some crosslinking is introduced into the sheets with a resultant increase in mechanical strength. This material in sheet form is valuable where the aqueous solution of uranium is a pulpy one, e.g., those from leaching ores; the solid particles are kept in suspension by an upward gas flow. Two examples are given of this method; in both cases, treated 0.05-in. and 0.006-in. sheets in contact with a solution of l g/l U/sub 3/O/sub 8/ had a U/sub 3/O/sub 8/ uptake on the order of 1.2 mg/cm/sup 2/.
