<p>Filter media containing an impregnant obtained by pre-reacting an amine functional material with a transition metal to form an amine-metal coordination complex. The complexed amine is much more compatible with amine sensitive co-impregnants or amine sensitive substrates. Additionally, even though the amine is complexed, the impregnant retains high activity for the removal of cyano-containing vapors and other contaminants for which amines have a filtering efficacy. Advantageously, therefore, the filter media may be used to remove cyano-containing vapors or other amine-targeted contaminants from air and other harmful gases in the presence of metal-based catalysts (such as those catalysts comprising platinum, gold or other active transition metals) without the undesirable effect of unduly inhibiting or poisoning the metal-based catalysts. The amine-containing coordination complex is also more compatible with substrates having electret characteristics as compared to otherwise identical amine material that is not complexed.</p> |
