A new chemosensor based on antipyrine derived Schiff's base (L) was synthesized by a reaction of antipyrene carboxaldehyde with 4-nitro phenylhydrazine. The probe L showed a color change toward Cu2+ from pale yellow to colorless. The detection limit of 0.42 μM for Cu2+ was below the World Health Organization (WHO) guideline for drinking water (31.5 μM). The probe L exhibits a 1:2 complex formation
通过安替芘甲醛与4-硝基苯肼反应合成了一种基于安替比林衍生席夫碱( L)的新型化学传感器。探针L显示出朝向Cu 2+的颜色从淡黄色变为无色。Cu 2+的检测限为 0.42 μM,低于世界卫生组织 (WHO) 饮用水指南 (31.5 μM)。探针L显示出与Cu 2+的1:2络合物形成。探针在 4-10 的 pH 范围内工作,不会干扰竞争离子。该探针已成功应用于定量水和药物样品中的Cu 2+。L与Cu 2+的结合机理通过使用 FTIR、质量和 DFT 分析来表征。总体而言,探针L展示了检测水相中Cu 2+含量的前景和潜力。
