摘要
通过溶剂热法合成了均苯三甲酸钪配位聚合物[MIL-100(Sc)],并将染料曙红Y负载框架物成功构筑荧光传感器EY@MIL-100(Sc)。采用PXRD、红外表征了产物结构,研究了EY@MIL-100(Sc)的荧光性质,并识别检测水中硝基芳香化合物。结果表明:EY@MIL-100(Sc)对4-硝基苯酚(4-NP)的检测表现出高灵敏度和选择性,KSV为2.78×10^(4)L/mol,检测限为0.42μmol/L,且有良好的可回收性能。EY@MIL-100(Sc)荧光识别硝基芳香化合物的机理归属于光诱导电子转移和共振能量转移共同作用。
The complex MIL-100(Sc)was synthesized by solvothermal method,and the fluorescent sensor was successfully constructed with the framework supported by eosin EY@MIL-100(Sc).The product structure was characterized by PXRD and IR.EY@MIL-100(Sc)was studied and nitro aromatic compounds were detected and identified.The results showed that EY@MIL-100(Sc)had high sensitivity and selectivity for the detection of 4-NP,and the Ksv was 2.78×10^(4)L/mol,detection limit was 0.42 umol/L,and has good recyclability.In addition,The EY@MIL-10o(Sc)mechanism of fluorescence recognition of nitroaromatic compounds was attributed to the joint action of photoinduced electron transfer and resonance energy transfer.
