ABSTRACT:
Novel compositions are prepared by impregnating activated alumina with sodium permanganate and a basic sodium compound. When used as a granular filter material in combination with a tobacco product as in a smoking article comprising a cigarette in combination with the filter materials, nitrogen oxides can be significantly reduced in the smoke obtained from the tobacco product after the filter material is stored for long periods of time in the presence of the volatile components of the tobacco product and/or moisture. Activated carbon may also be combined with the composition.
