Molecular Imprinting of Theophylline in Acrylonitrile-acrylic Acid Copolymer Membrane

Abstract

Abstract Molecular size of Theophylline was imprinted in ultrafiltration membrane of poly(acrylonitrile-co-acrylic acid), when the membrane was prepared by phase inversion method. Evidence was presented by the permeation experiments that the Theophylline solute binds more strongly to the imprinted membrane.
