Composition comprising metal-ion sequestrant

摘要

This invention relates to a composition of matter comprising a functionalized mordant polymer comprising a cationic polymer having an adsorbed metal-ion sequestrant, wherein the metal-ion sequestrant has a stability constant greater than 10¹⁰ with iron (III). It further relates to an article comprising said composition and a method of removing target metal-ions from an environment comprising contacting the environment with said composition.
