Abstract
Compositions that can be used to adsorb low concentration, of unwanted or target substances from a dynamic fluid stream or from an enclosed static vapor phase. Such adsorbency can be obtained with thermoplastic materials used in the form of bulk polymer or a film, fiber, web, woven fabric, non-woven fabric, sheet, packaging and other such structures including or surrounding the enclosed volume. The concentration should be reduced to non-offensive sensed limits or a limit that does not produce a biological response.
Claims22
An adsorbent comprising a nonwoven fabric having a coating, the coating comprising a solid surface, the solid surface comprising an interface with a gas or vapor phase, the solid surface comprising:
- a. ferric hydroxide;
- and
- b. an uncomplexed polyethylenimine
- wherein the adsorbent is adapted for adsorbing unwanted or target substances from the gas or vapor phase.
