Abstract

A novel approach for the detection and separation of toxic ions was successfully developed via the introduction of competitive reactions into a long-alkyl-chained acylhydrazone-based coumarin supramolecular polymer, chemosensor OGC (3%, n-BuOH/HO), which showed sequential detection and separation of CN, Fe and S, Ag in the gel state with high selectivity and sensitivity. Moreover, the ion-responsive films were prepared for the convenient and continuous detection of CN, Fe and S, Ag in water solution.

摘要

通过将竞争反应引入基于长链烷酰基腙的香豆素超分子聚合物（化学传感器 OGC（3%，n-BuOH/HO））中，成功开发了一种用于检测和分离有毒离子的新方法。该化学传感器对 CN、Fe 和 S、Ag 具有高选择性和灵敏度，可在凝胶状态下进行顺序检测和分离。此外，还制备了离子响应膜，以便于在水溶液中方便连续地检测 CN、Fe 和 S、Ag。
