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.
