                                Technical Abstract: Synthetic sorbents offer a means to develop more robust materials to detect analytes in complex matrices, including methods to detect naturally occurring contaminants in agricultural commodities.  Patulin is a mold metabolite associated with rotting apples and poses health risks to humans and animals.  Beta-cyclodextrin-based polyurethane polymers were synthesized and evaluated for the ability to bind the toxin patulin under aqueous conditions.  Freundlich isotherm analysis indicates a degree of heterogeneity in the affinity of the binding site population.  Crosslinked polymers with tolylene 2,4-diisocyanate were suitable for the solid phase extraction and LC-analysis of patulin from apple juice.  Studies of binding modes of patulin with the ß-cyclodextrin component using the PM3 semi-empirical method identified several preferred complexes possessing intermolecular hydrogen bond interactions.  These nanoporous polymers exhibit favorable properties to assist the detection of patulin in aqueous solutions.
