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.
Claims8
A composite shape-retaining structure comprised of a batting of randomly arranged intercontacting polyester fibers bonded together at their intercontacting sites, thereby defining communicating interstitial spaces, said spaces confining granules of a polymer having selective affinity for dissolved heavy metals, said batting having a uniform thickness in the range of about 0.5 to 2.5 inches and a basis weight of 1.5 to 12 ounces/square yard.
