英文摘要	Based on the reversible recognizing reaction between insoluble beta-cyclodextrin polymer (beta-CDP) and bisphenol A (BPA), a bifurcated optical fiber chemical sensor has been proposed for continuous monitoring of BPA. When immobilized in a plasticized poly(vinyl chloride) membrane of 5 mu m thickness, beta-CDP extracts BPA from aqueous solutions into the bulk membrane phase and reacts with the analyte to form an inclusion complex with high fluorescence efficiency. Formation of the complex gives a significant enhancement of the intrinsic fluorescence (lambda(ex)/lambda(em) = 286 nm/312 nm) of BPA which is suitable for signaling the occurrence of the host-guest recognizing interaction. The fluorescence sensor exhibits a dynamic detection range from 6.0 x 10(-6) mol/L to 1.0 x 10(-3) mol/L with a detection limit of 1.0 x 10-6 mol/L. The high selectivity of the sensor toward BPA depends on the synergistic shielding effect by beta-CD units and an optimal space-matching between the host and the guest. The proposed sensor was successfully used for the determination of BPA in water samples. (c) 2005 Elsevier B.V. All fights reserved.
