A SORPTIVE-FILTRATION SYSTEM FOR THE CAPTURE OF WATERBORNE AND AIRBORNE CONSTITUENTS

摘要

An adsorptive-filtration media (12) for the capture of waterborne or airborne constituents. The media comprises a granular substrate and an amphoteric compound bonded to the substrate in the presence of a crystal inhibiting agent. The media can also comprise a substrate having a specific gravity of less than 1.0 and an amphoteric compound bonded to the substrate. Another media comprises a substrate with a specific surface area of greater than 0. 1 m<sup
