Abstract
At lower temperatures an acidic molecular sieve adsorbent preferentially adsorbs water and basic organic nitrogen compounds over weakly basic organic nitrogen compounds such as nitrites. Elevated temperatures improve the capacity of acidic molecular sieve adsorbents to adsorb nitrites in the presence of water.
