摘要

设计了一种基于水杨醛的新型传感器N'-(5-溴-2-羟基苄基)-4-甲基苯并肼(P4)，并利用紫外可见光谱对其对多种金属离子的传感能力进行了评价。采用紫外-可见、红外、1H-NMR、13C-NMR谱和质谱对P4的结构进行了表征。紫外-可见吸收光谱研究表明，P4在多种过渡金属离子存在下对Cd2+和Ni2+离子具有选择性传感能力。结果表明，该方法对Cd2+和Ni2+的检出限分别为3.14µM和0.92µM。此外，化合物P4完全实现了模拟样品中Cd2+和Ni2+的检测。

Salicylaldehyde based Schiff base as a selective and sensitive chemosensor for Cd2+ and Ni2+ ions

A new salicylaldehyde-based sensor N'-(5-bromo-2-hydroxybenzylidene)-4-methylbenzohydrazide (P4) was designed, and its sensing ability towards various metal ions was assessed using UV-visible spectroscopy. The structure of P4 was spectroscopically characterized by UV-Visible, Infrared, 1H-NMR, 13C-NMR spectroscopy and mass spectrometry. UV-Visible absorption spectral study showed selective sensing ability of P4 for Cd2+ and Ni2+ ions in presence of diverse transition metal ions. The results revealed that the detection limit for Cd2+ and Ni2+ was 3.14 µM and 0.92 µM, respectively. Moreover, the compound P4 was fully implemented for detection of Cd2+ and Ni2+ in simulated samples.
