Polyvinylpyridinium anion-exchangers for recovery of technetium and plutonium anions

Described are anion-exchange materials having extraordinarily high affinity for plutonium anions such as plutonium (IV), and technetium anions such as pertechnetate. Preferred inventive resins are highly divinylbenzene-crosslinked polyvinylpyridine resins exhibiting a macroreticular bead form, which...
