Abstract

Disclosed is a selectively permeable membrane using selective molecular recognition macromolecules using molecular recognition macromolecules which use an extremely thin molecular recognition resin membrane which, by allowing the permeation of a specified single kind of component from a mixed aqueous solution of various antibiotics, saccharides, amino acids, organic toxic substances and other organic compounds, is easily capable of fractional extraction or fractional removal, fractional isolation or detection, or quantitative analysis. A molecular recognition macromolecule membrane (11), whereon a template molecule of a specified compound molecule which is the object of fractionation or isolation has been molecularly imprinted, is formed on a porous support membrane (12) provided with a plurality of micropores having an internal diameter through which the specified compound molecule which is the object of fractionation or isolation can permeate, and the specified compound molecule is selectively permeated by the molecular recognition resin membrane (11), and the compound molecule is permeated from the micropores of the porous support membrane (12).
