Description

General description

Silver-exchanged zeolite selectively removes halogens from gas streams and also serves as catalyst.

Application

Silver-exchanged zeolite is used:

• As a catalyst in the low-temperature CO isotopic scrambling reaction.
• To capture radioiodine from the vapor phase, which is then thermally converted into silver sodalite.
