PROCEDIMENTO DI ATTIVAZIONE DELLE AMMINE SOLUBILI IN ACQUA MEDIANTE ALOGENI PER CATTURARE IL RADIO DIO DELLE CORRENTI DI ARIA

摘要

Gas adsorbent charcoals impregnated with an aqueous solution of the reaction product of a tertiary amine and elemental iodine or bromine are better than 99 per cent efficient in trapping methyl iodine131. The chemical addition of iodine or bromine to the tertiary amine molecule increases the efficiency of the impregnated charcoal as a trapping agent, and in conjunction with the high flash point of the tertiary amine raises the ignition temperature of the impregnated charcoal.
