摘　　要：为了方便快捷地检测铝离子,本文以7-羟基香豆素为原料合成了铝离子荧光化学传感器。通过质谱、核磁共振谱、紫外可见分光光度计等技术手段研究了传感器的结构和性能。结果表明,该传感器对铝离子有很好的选择性,其检出限为8. 5×10-8mol/L,其识别过程具有可逆性,同时,Job's plot曲线表明二者形成配位比为1∶1的稳定配合物。该研究对生物体及环境领域中铝离子的实时监测具有潜在的应用价值。For the sake of convenient and quick detection of aluminum ion,an aluminum ion fluorescent chemosensor was synthesized from 7-hydroxyl coumarin.Its structure was verified by mass spectrometry and nuclear magnetic resonance spectrum.The properties and structure of fluorescence chemosensor were characterized by mass spectrometry(MS),nuclear magnetic resonance spectroscopy(NMR),UV-vsisible absorption spectrum(UV-Vis).The results reveal that the sensor has good selectivity toward aluminum ion.The limit of detection is 8.5×10-8 mol/L,and the identification process is reversible.The Job′s plot indicates that the sensor and aluminum ion forms stable complex in 1∶1 ratio.Therefore,this fluorescent chemosensor has potential in real time monitoring aluminum ion in biological and environmental applications.
