摘要: A composition of matter comprising a permanganate salt adsorbed or chemisorbed onto a solid alkaline support useful in a method for irreversibly removing or decreasing the amount of formaldehyde in the atmosphere. The composition further provides a color change indication when the formaldehyde absorbing characteristic is exhausted. The composition can be employed in molded, pellet, particle or powder form as, for example, in a respirator filter cartridge.
