Comparison of sorption capacity of activated carbons, zeolites and industrial aluminum oxide with respect to nitric oxide (II) in the air

Abstract

This investigation studied the sorption of NO by activated carbons, zeolites and aluminum oxide at ambient temperature. It was found that γ-Al2O3 has the highest sorption capacity (45-50%). Among the studied activated carbons only AG-3 sample proved to be competitive with samples of γ-Al2O3. The NO sorption degree of the studied zeolites was less than 7%
