초록

Apparatus, process and article for treating a gas containing one or more of a chemical and/or biological contaminant. The process includes contacting the gas with an aggregate composition comprising an insoluble rare earth-containing compound to form a gas depleted of chemical and active biological contaminants. The insoluble rare earth-containing compound can include one or more of cerium, lanthanum, or praseodymium. The composition comprises no more than two elements selected from the group consisting of yttrium, scandium, and europium when the aggrega...
