Anionic, acidic, and metal ions are common contaminants in water and cause serious concerns for human and aquatic life. With the goal of rapid detection of analytes, we herein design a new array of ligand 5-(4H-1,2,4-triazol-4-yl)pyridin-3-ol-linked silver coordinated metal–organic frameworks Ag-MOFs as a promising sensor for Cr₂O₇^2–, MnO₄^–, humic acid (HA), and Fe³⁺ ions down to the micro level. Furthermore, as evidenced by luminescence, excitation-emission matrix (EEM) spectroscopic, and PXRD measurements, designed metal–organic frameworks (MOFs) can be fast, stable, and reusable for analyte detection in water.

触觉传感器：用于检测 Cr2O72–、MnO4–、腐殖酸和 Fe3+ 离子的羟基装饰银金属有机框架

阴离子、酸性和金属离子是水中常见的污染物，对人类和水生生物造成严重影响。为了快速检测分析物，我们在此设计了一个新的配体阵列 5-(4 H -1,2,4-triazol-4-yl)pyridin-3-ol-linked silver coordinated metal-organic frameworks Ag- MOF作为 Cr ₂ O ₇^2–、MnO ₄^–、腐殖酸 (HA) 和 Fe ³⁺离子低至微观水平的有前景的传感器。此外，正如发光、激发发射矩阵 (EEM) 光谱和 PXRD 测量所证明的那样，设计的金属有机框架 (MOF) 可以快速、稳定且可重复用于水中的分析物检测。
