TLDR
In this paper, a process for the removal of iodine and organic iodine compounds having a low number of carbon atoms from gases and/or vapours is described, in which the gases or vapours containing II compounds are passed through a layer of binder-free silver-exchanged molecular sieve granules of the structural type of faujasite.Abstract:
Process for rapid and almost complete removal of iodine and/or organic iodine compounds having a low number of carbon atoms from gases and/or vapours, in which the gases or vapours containing iodine and/or iodine compounds are passed through a layer of binder-free silver-exchanged molecular sieve granules of the structural type of faujasite.read more

Method for extracting gaseous iodine
TL;DR: In this article, a method for extracting gaseous iodine was proposed, which comprises an absorbing step, wherein the absorbing step comprises the detailed steps of: (S1) absorbing the iodine: adoptinga silver-loaded mordenite absorbing column to absorb the iodine from a gaserous phase generated by operation of a reactor; (S2) desorbing the iodine, adopting mixed solution of hydrazine hydrate and sodium hydroxide to desorb the iodine on the silver loaded Mordenitic absorbing column in the step (S 1); (S

Method for treating a nuclear process off-gas stream
Dallas T. Pence,Chun-Chao Chou +1 more
TL;DR: In this paper, a method for selectively removing and recovering the noble gas and other gaseous components typically emitted during nuclear process operations is presented. But the method is adaptable and useful for treating dissolver off-gas effluents released during reprocessing of spent nuclear fuels whereby to permit radioactive contaminant recovery prior to releasing the remaining off-gases to the atmosphere.
