ABSTRACT:
The present invention relates to compounds and methods for removing metals, e.g., ionic cobalt from an electroless plating operation, preferably to levels less than 5 ppm. The metals can then be either landfilled or regenerated for electrowinning and reuse. The invention utilizes an ion exchange media comprised of a silica backbone and functionalized with phosphonate groups.
