Retention of sup 131 I Volatilized from Aqueous Solutions by Sorbents

摘要

By far the largest proportion of the I-131 that was volatilized from alkaline aqueous solutions was in a form whose retention by various sorbents was lower than that of I sub 2 , but higher than that of CH sub 3 I. This form is called 'HOI' although no direct identification exists. With all the fresh impregnated activated carbons investigated, the retention of 'HOI' was higher than 99% at a residence time of 0.1 s. The influence of purging was insignificant.
