双酚A（BPA）是一种致癌物质，可干扰人体内分泌系统。本文基于荧光共轭聚合物PPESO 3构建了一种新型的BPA荧光传感器。在HRP和H_2O_2存在下，BPA的氧化产物能猝灭PPESO_3，其猝灭光强度与BPA浓度在1-100 μ mol/L范围内成正比，检出限为4 × 10 ~（-7）mol/L。该方法用于8种食品包装样品中BPA的测定，结果令人满意。所提出的方法具有潜在的食品或食品包装样品中双酚A的测定。(C)2015爱思唯尔有限公司版权所有。
Bisphenol A (BPA) is a kind of carcinogen, which can interfere with the body's endocrine system. In this paper, a new kind of fluorescent sensor for BPA detection was established based on the fluorescent conjugated polymer PPESO3. The oxidative product of BPA is able to quench PPESO3 in the presence of HRP and H2O2, and the quenched PL intensity of PPESO3 was proportionally to the concentration of BPA in the range of 1-100 mu mol/L with a detection limit of 4 x 10(-7) mol/L. The proposed method has been applied to detect BPA in eight food packaging samples with satisfactory results. The proposed method has the potential for the assay of BPA in food or food packaging samples. (C) 2015 Elsevier Ltd. All rights reserved.
