摘要

The use of a resorcln [4] sandy, a method to form a complex of nitrosu00c8nio, complex of the same, complex, use of the same, methods for trapping one or more nitrogen oxides, to absorb one or more oxides of nitrogen from tobacco smoke, and to absorb selectively the products of CO Mbustu00e3o containing nitrogen oxide in tobacco smoke, the filter element, article for smoking.Apparatus for filtration and filter of smoke or a wrapper or a component of an article for smoking. The present invention relates to the use of resorcin [4] arenos to absorb one or more nitrogen oxides in a medium containing nitrogen oxide.Additional aspects of the invention relate to complex in ~ + ~ with resorcin [4] arenos and filter elements which comprise one or more resorcin [4] arenos.
