Claim Text:
1. A method of reducing amounts of metal in a fluid comprising the steps of: a) contacting at least a portion of a substrate with an alkaline, aqueous solution under oxidative conditions, the solution comprising a surface-modifying agent according to Formula I: wherein each of R wherein x ranges from 0 to 10 and wherein y ranges from 0 to 10, provided that x or y is at least 1; and b) contacting the surface-modified substrate with a reactive moiety, wherein the reactive moiety reacts with and is bound to the surface-modified substrate forming a moiety-modified substrate c) positioning the moiety-modified substrate in a fluid with metal, whereby the moiety-modified substrate binds to at least a portion of the metal, thereby reducing the amounts of metal in the fluid.
