Novel macromolecules for filtering contaminants from water and non-aqueous solutions. Molecules such as polyethyleneimine (PEI) may be functionalized, cross-linked, and/or quaternized to improve their binding capacity or selectivity with particular water contaminants such as bromide, nitrate, and sulfate. The macromolecules may be either recyclable or non-recyclable, and may be recovered or separated from water using means such as ultrafiltration, flocculation, or immobilization on a substrate. |
