Inventors: Murray GM
Patent Title: Method and apparatus for environmental phosphate/nitrate pollution removal using a selectively permeable molecularly imprinted polymer membrane
Publication date: 2003
Publication number: US20030059346

Abstract: The invention comprises a selectively permeable molecularly imprinted polymer membrane for the removal of phosphate/nitrate anions from solutions. The polymeric membrane will be synthesized with ingredients for both selective binding and improved permeability. The selective binding site will be prepared by using ferric ion imprinting. Permeability is improved by using a polyester that associates with the metal ions; the polyester will be removed from the membrane by the same acid treatment used to remove the ferric ion. The polyester creates channels directing the ion migration to the imprinted sites, thus, increasing flux but maintaining selectivity.
