Abstract
A novel method for separating a target substance, for example, metal ion, drug or biological component is provided. According to the method, the surface of a packing undergoes a chemical or physical environmental change under a physical stimulus so that the interaction of a substance interacting with the target substance is reversibly changed in an aqueous solution, thus effecting separation.
Claims4
A material for use in separation methods comprising a stimulus-responsive polymer and a substance interacting specifically with a target substance, wherein said stimulus-responsive polymer undergoes a structural change upon a physical stimulus such that the interaction of the substance interacting specifically with the target substance is affected, thereby causing a reversible change in the interaction force with the target substance due to the physical stimulus.
