DIALYSIS MEMBRANE

摘要

The issue is to provide a dialysis membrane using an extremely thin molecular identification membrane with which fractional extraction or fractional removal, fractional isolation or detection, or quantitative analysis of one specific component from a mixed aqueous solution of various antibiotics, sugars, amino acids, organic toxins or other organic compounds is easily accomplished using dialysis. A molecular identification resin membrane (11) that has been molecularly imprinted with a template molecule for a specific substance to be fractionated or isolated is formed on a porous support membrane (12), which is provided with many microscopic holes having an internal diameter through which molecules of the specific compound to be fractionated or isolated can pass. Molecules of the specific compound are selectively dialyzed by the molecular identification resin membrane (11) and the molecules of the compound are allowed to pass through the micropores of the porous support membrane (12).
