Abstract

MIL-101-OH, a hydroxyl-functionalized metal–organic framework (MOF), was synthesized as a nanostructured adsorbent to detect and eliminate methylene blue (MB) and cefixime (CEF) from aqueous solutions. To improve its interaction with pollutants, MIL-101 was post-synthetically modified with hydroxyl group. BET analysis showed a specific surface area of 1367 m²/g, and FTIR and XRD analyses verified the structural integrity and successful functionalization. The uniform distribution of particle sizes was shown by SEM imaging. To enable detection based on changes in the refractive index, the functionalized MOF was also used as a coating material on an optical fiber sensor. CEF and MB had maximum adsorption capacities of 328 mg/g and 358 mg/g, respectively. The results demonstrate the potential of MIL-101-OH for simultaneous adsorption and optical sensing applications in water treatment. The sensor demonstrated a linear dynamic range of 0–10 mg/L with response times of 75and 32 s for CEF and MB, respectively.

羟基功能化MIL-101纳米结构对水溶液中头孢克肟和亚甲基蓝的检测与吸附

合成了羟基功能化金属有机骨架（MOF） MIL-101-OH作为纳米结构吸附剂，用于检测和去除水溶液中的亚甲基蓝（MB）和头孢克肟（CEF）。为了改善其与污染物的相互作用，对MIL-101进行了羟基修饰。BET分析显示比表面积为1367 m2/g， FTIR和XRD分析证实了结构的完整性和成功的功能化。扫描电镜（SEM）成像结果表明，颗粒粒径分布均匀。为了实现基于折射率变化的检测，功能化的MOF还被用作光纤传感器的涂层材料。CEF和MB的最大吸附量分别为328 mg/g和358 mg/g。结果表明MIL-101-OH在水处理中具有同时吸附和光学传感应用的潜力。该传感器的线性动态范围为0-10 mg/L，对CEF和MB的响应时间分别为75和32 s。

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
