Broad spectrum filter system including tungsten-based impregnant and being useful for filtering contaminants from air or other gases

摘要：

Filter systems that are effective against a broad range of contaminants including HCN, cyanogen chloride (CK), acid contaminants. and basic contaminants such as ammonia without the need (but with the option, if desired) for using molybdenum or chromium containing materials. The filtering systems of the present invention include a tungsten-based material and other impregnants incorporated into a substrate such as filter media particles.

摘要（中）：

过滤系统对广泛的污染物有效，包括HCN，氯化氰（CK），酸性污染物。和碱性污染物如氨，而不需要（但是如果需要，也可以选择）使用含钼或铬的材料。本发明的过滤系统包括钨基材料和掺入到诸如过滤介质颗粒的基材中的其它浸渍剂。
