A filter for removing contaminants from air. The filter includes (a) a substrate that does not have any volatile ammonia on the surface thereof; (b) copper that has been impregnated onto the substrate; and (c) molybdenum and/or tungsten that has been impregnated onto the substrate. The filter can be made using an aqueous solution(s) that contains one or more of a first copper salt and a second salt that include a polynuclear anion that contains molybdenum, tungsten, or both. Because the metals can be impregnated onto the substrate surface without using an ammonium-based solution, the need to manage ammonia off-gassing is avoided. Further, no volatile ammonia would be present on the resulting substrate surface.

La présente invention concerne un filtre pour lélimination de contaminants de lair. Le filtre comporte (a) un substrat qui ne contient pas dammoniac volatile à sa surface ; (b) du cuivre qui a été imprégné sur le substrat ; et (c) du molybdène et/ou du tungstène qui a été imprégné sur le substrat. Le filtre peut être réalisé en utilisant une/des solution(s) aqueuse(s) contenant un ou plusieurs parmi un premier sel de cuivre et un second sel comprenant un anion polynucléaire qui contient du molybdène, du tungstène, ou les deux. Étant donné que les métaux peuvent être imprégnés sur la surface du substrat sans utiliser une solution à base dammoniac, on peut éviter la nécessité de procéder à un dégazage dammoniac. En outre, il ny aura pas dammoniac volatile sur la surface du substrat obtenu.
