ABSTRACT:
A method for reducing contaminant concentrations in a fluid stream including the steps of forming a metal-complexed material having a surface suitable for exchange with the contaminant, contacting the fluid stream with the metal-complexed material, immobilizing at least a portion of the contaminant on the surface of the metal-complexed material, and regenerating the metal-complexed material so as to remove the contaminant from the surface of the metal-complexed material. The metal-complexed material is formed by the encapsulating of a core of ferromagnetic material with an ion exchange material. The metal-complexed material is magnetically affixed to a metallic mesh retaining surface.
