A novel nanosensor based on CdSe quantum dots (QDs) capped with 8-hydroxyqunoline (HQ) was developed for Al3+ ions determination in aqueous solutions. The method is based on the fluorescence enhancement of the HQ functionalized QDs in the presence of Al3+ ions, due to the strong interaction between Al3+ and HQ. Prepared nanosensor exhibited an acceptable selectivity and sensitivity for Al3+ ions in
开发了一种新型的基于CdSe量子点(QDs)的纳米传感器,该量子点被8-羟基喹啉(HQ)覆盖,用于测定水溶液中的Al 3+离子。该方法是基于HQ的荧光增强官能化在Al的存在的QD 3+离子时,由于与Al之间的强相互作用3+和HQ。制备的纳米传感器在存在其他金属离子的情况下对Al 3+离子表现出可接受的选择性和灵敏度。Log(I / I 0)对Log [Al 3+ ]的图在0.02–3.0 mM范围内显示出良好的线性,该方法可用于检测水溶液中的Al 3+离子浓度。
