Abstract
Irregularly shaped granules of a polymer capable of rapidly removing trace levels of toxic heavy metals from water, but posing high resistance to the flow of water, are trapped within interstitial spaces of a shape-retaining porous matrix of intercontacting fibers, forming a composite structure useful in on-the-run water remediations. The composite structure is produced by generating the granules within the matrix.
