In the present study, a fluorescent sensor L for sensing of Ce3+ ion was designed and characterized by XRD, 1HNMR, and FTIR. Its fluorescence behavior towards metal ion was examined by fluorescence spectroscopy. Chelation-enhanced fluorescence was shown by the sensor L upon interaction with Ce3+ ion. This fluorescent sensor exhibits high sensitivity and selectivity towards Ce3+ ion in acetonitrile solution, forming 2 : 1 (L : M) complex as determined by Job’s plot. Association constant was found to be estimated from the Benesi-Hildebrand plot. No significant interference was observed in the presence of other studied alkali, alkaline, and transition metal ions. A rapid response was observed when employed for the determination of Ce3+ ion in spiked water samples with a limit of detection equal to .

基于席夫的荧光ON传感器L的合成及其在水中介质中铈的选择性测定中的应用

在本研究中,设计了用于感测Ce 3+离子的荧光传感器L,并通过XRD,1 HNMR和FTIR对其进行了表征。通过荧光光谱检查了其对金属离子的荧光行为。与Ce 3+离子相互作用时,传感器L显示出螯合增强的荧光。该荧光传感器对乙腈溶液中的Ce 3+离子具有很高的灵敏度和选择性,形成了2:1(L:M)的络合物,由Job's图确定。发现关联常数为根据Benesi-Hildebrand图进行估算。在其他研究的碱金属,碱金属和过渡金属离子的存在下,未观察到明显的干扰。当用于加标水样品中Ce 3+离子的测定时,观察到快速响应,检出限等于
