Poly-β-Cyclodextrins: Multifunctional Polymer Support for the Hydrolysis and Removal of Methyl Parathion
Published online by Cambridge University Press: 15 February 2011
Abstract
Microparticles (32-53 μm) of cross-linked poly-β-Cyclodextrin (PCD) having a bifunctional hexyl spacer were prepared. PCD served as an insoluble robust matrix, which is chemically inert in acidic and basic media while preserving accessibility of pesticide methyl parathion (MPT) and its hydrolysis product p-nitrophenol (p-NP) to cyclodextrin cavities. The multi-utility of PCD was demonstrated as a stable biomaterial for adsorption of MPT and p-NP through inclusion phenomena and as a single unit system suitable for casting alternate enzyme/polyelectrolyte multilayers.
