Abstract

The desorption of rhenium from an A172 anion exchanger with an ammonia solution has been studied. A172 and A170 anion exchangers have been investigated with infrared spectroscopy. The difference in their structures has been revealed so that A172 can be assigned to a medium basic anion exchanger type. The reason for the low desorption of rhenium from the A172 anion exchanger has been determined.
