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.
Claims7
A separation method comprising applying a physical stimulus to a material containing a ligand interacting with a target substance, to cause a chemical or physical environmental change in the material wherein the interaction between the ligand and the target substance is reversibly changed, thus effecting separation and wherein the material comprises a composite material containing a stimulus-responsive polymer and a ligand interacting specifically with a target substance, wherein said stimulus-responsive polymer undergoes a structural change upon the application of the physical stimulus such that the interaction of the target substance and ligand is affected, thereby causing a reversible change in the interaction force with the target substance due to the physical stimulus.
