Abstract
The invention pertains to a method for simultaneously removing metallic ions and particulate material from a pH neutral solution using particle-removing membranes (e.g., ultra high molecular weight polyethylene) having immobilized ligands that possess the capacity and high equilibrium binding constants for ion removal. The method is particularly useful for simultaneously filtering/purifying deionized water.
