1. N-HYDROXYPOLYVINYLPYRIDINIUM TYPE ANION EXCHANGERS 2. URANIUM, PLUTONIUM, BERYLLIUM AND ZIRCONIUM COMPLEXES OF PYKIDINE-N-OXIDE-2-CARBOXYLIC ACID

摘要

Crosslinked N-hydroxypolyvinylpyridinium ion exchangers were pre¬pared in an attempt to utilize the specificity which N-oxides show towards heavy metals, uranium in particular. However, the polymers obtained behaved as ordinary anion exchangers, somewhat less basic than Dowex-2. The main advantage of the new exchanger is its high exchange rate.
