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.
Claims14
A method of making an adsorbent, the method comprising, in order:
- combining an aqueous floe of ferric hydroxide with an aqueous solution of an uncomplexed polyethylenimine to form a coating composition;
- applying the coating composition to a substrate;
- and
- drying the coating composition on the substrate to form the adsorbent.
