the detection of Cd(II) and Co(II) metal ion using 1,2,3-triazole linked fluorescein chemosensor (FLT). The studies were performed in 4:1 ethanol/water (v/v) solution and present an excellent “turn-off” and “turn-on” response with the Cd(II) and Co(II) metal ions, respectively. The need to develop FLT sensor was propelled by the high toxicity of Cd(II) and Co(II) ions in water and their competitive detection
该报告提出了一种独特的“开关”系统,该系统使用1,2,3-三唑连接的荧光素化学传感器(FLT)检测Cd(II)和Co(II)金属离子。研究是在4:1乙醇/水(v / v)溶液中进行的,分别显示了Cd(II)和Co(II)金属离子的出色“关闭”和“开启”响应。Cd(II)和Co(II)离子在水中的高毒性以及用肉眼在金属离子混合物的水溶液中进行竞争性检测,推动了对FLT传感器的开发需求。包含1,2,3-三唑的FLT探针具有高选择性和特异性,该探针由荧光素主链组成,这归因于光电子转移(PET)机制。
