【摘要】 以MOFs材料MIL-96为载体，烯丙基荧光素为荧光基团，甲基丙烯酸为功能单体，乙二醇二甲基丙烯酸酯为交联剂，偶氮二异丁腈为引发剂，采用沉淀聚合法制备了一种用于检测罗丹明B的表面分子印迹荧光传感器（MIL-96@AF-SMIPs）。采用扫描电镜、傅里叶变换红外光谱、X射线衍射等对传感器进行表征，表明已成功合成表面分子印迹荧光传感器。在检测罗丹明B的过程中，其荧光强度之比I580/I522与罗丹明B浓度（0～0.5μmol/L）具有良好的线性关系（R~2=0.999），检出限为8.03 nmol/L。此外，该传感器具有选择性高、重复使用性好以及荧光稳定性良好的优点。在检测实际样品时，罗丹明B的回收率为94.23%～109.07%，相对标准偏差小于3.75%。该工作为罗丹明B的高效快速检测提供了一种可行的方法。更多还原

【Abstract】 In this paper, using the MOFs material of MIL-96 as the carrier, allyl fluorescein as the fluorescent group, methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the crosslinking agent, azobisisobutyronitrile as the initiator, a novel surface molecularly imprinted fluorescence sensor(MIL-96@AF-SMIPs) for the detection of Rhodamine B was prepared by precipitation polymerization. The sensor was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction, which proved the surface molecularly imprinted fluorescence sensor has been successfully synthesized.In the detection of Rhodamine B, the fluorescence intensity ratio I580/I522 showed a good linear relationship with the concentration of Rhodamine B in the range of 0-0. 5 μmol/L(R~2=0. 999). The detection limit was 8. 03 nmol/L. In addition, the sensor exhibited high selectivity, good reusability and excellent fluorescence stability. The recovery of Rhodamine B in real sample analysis was 94. 23%-109. 07%, and the relative standard deviation was less than 3. 75%. This study provides a feasible method for efficient and rapid detection of Rhodamine B.更多还原
