| 英文摘要 | A bifurcated optical fiberchemical sensor for continuous monitoring of bisphenol A (BPA) has been proposed based on the fluorescence quenching (lambda(ex)/lambda(em) = 286/390 nm) of pyrene/dimethyl beta-cyclodextrin (HDM-beta-CD) supramolecular complex immobilized in a plasticized poly(vinyl chloride) (PVC) membrane, in which pyrene served as a sensitive fluorescence indicator probe. The decrease of the fluorescence intensity of pyrene/HDM-beta-CD complex upon the addition of BPA was attributed to the displacement of pyrene by BPA, which has been utilized as the basis of the fabrication of a BPA-sensitive fluorescence sensor. The response mechanism of the sensor was discussed in detail. The sensor exhibited a dynamic detection range from 7.90 x 10(-8) to 1.66 x 10(-5) mol L-1 with a detection limit of 7.00 x 10(-8) mol L-1, and showed excellent reproducibility, reversibility, selectivity, and lifetime. The proposed sensor was successfully used for the determination of BPA in water samples and landfill leachate. (c) 2005 Elsevier B.V. All rights reserved. |
