Initial Effects of NO x on Idodine and Methyl Iodine Loading of AgZ and Aerogels
This initial evaluation provides insight into the effect of NO on the adsorption of both I 2 and CH 3I onto reduced silver-exchanged mordenite (Ag 0Z). It was determined that adsorption of CH 3I onto Ag 0Z occurs at approximately 50% of the rate of I 2 adsorption onto Ag 0Z, although total iodine capacities are comparable. Addition of 1% NO to the simulated off-gas stream results in very similar loading behaviors and iodine capacities for both iodine species. This is most likely an effect of CH 3I oxidation to I 2 by NO prior to contact with the sorbent bed. Completion of tests including NO 2 in the simulated off-gas stream was delayed due to vendor NO 2 production schedules. A statistically designed test matrix is partially completed, and upon conclusion of the suggested experiments, the effects of temperature, NO, NO 2, and water vapor on the sorption of CH 3I and I 2 onto Ag 0Z will be able to be statistically resolved. This work represents progress towards that aim.
