Abstract

A particle loaded, porous, fibrous compressed or fused article comprises a nonwoven fibrous polymeric web, which prefer-ably is thermoplastic, melt-extrudable, and pressure-fusible blown microfibrous web, and sorptive particles enmeshed in said web, the particle loaded fibrous article has a Gurley number of at least two seconds, and the article is useful in separation science.
A method of preparation of the article and method of use is also disclosed.
