Abstract
Official abstract text for this publication.
Disclosed is a method for selectively binding and separating phosphate anions from a liquid medium by providing a cross-linked molecularly imprinted polymer including cross-linked chitosan having selective binding affinity for phosphate ions, phosphate containing molecules, or a combination of both.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for selectively binding and separating phosphate anions from a liquid medium, said method comprising: (a) providing a cross-linked molecularly imprinted polymer, the cross-linked molecularly imprinted polymer comprising: cross-linked molecularly imprinted chitosan having complementary molecular cavities that have a selective binding affinity for phosphate ions, phosphate-containing molecules, or a combination of both; and (b) contacting the cross-linked molecularly imprinted polymer with the liquid medium, wherein any phosphate ions, phosphate-containing molecules, or a combination of both present in the liquid medium are selectively removed from the liquid medium and sequestered in the cross-linked molecularly imprinted polymer. 2. The method of claim 1 , wherein the liquid medium is an aqueous medium. 3. The method of claim 1 , wherein the liquid medium is passed through a column or bed comprising one or more of the cross-linked molecularly imprinted polymers.
