In the present study, preparation of CuBTC-monopol monoliths for use within the microchip solid phase extraction was undertaken through a 20-min UV lamp-assisted polymerization for 2,2-dimethoxy-2-phenyl acetophenone (DMPA), butyl methacrylate (BMA), and ethylene dimethacrylate (EDMA) alongside inclusion of the porogenic solvent system (1-propanol and methanol (1 : 1)). The resultant coating underwent coating using CuBTC nanocrystals in ethanolic solution of ethanolic solution of 1,3,5-benzenetricarboxylic acid (H₃BTC, 10 mM) and 10 mM copper(II) acetate Cu(CH₃COO)₂. This paper reports enhanced extraction, characterization, and synthesis studies for porous CuBTC metal organic frameworks that are marked by different methods including SEM/EDAX analysis, atomic force microscopy (AFM), and Fourier-transform infrared spectroscopy (FT-IR). The evaluation of the microchip’s performance was undertaken as sorbent through retrieval of six toxic dyes (anionic and cationic dyes). Various parameters (desorption and extraction step flow rates, volume of desorption solvent, volume of sample, and type of desorption solvent) were examined to optimize dye extraction using fabricated microchips. The result indicated that CuBTC-monopol monoliths were permeable with the ability of removing impurities and attained high toxic dye extraction recovery (83.4–99.9%). The assessment of reproducibility for chip-to-chip was undertaken by computing the relative standard deviations (RSDs) of the six dyes in extraction. The interbatch and intrabatch RSDs ranged between 3.8 and 6.9% and 2.3 and 4.8%. Such features showed that fabricated CuBTC-monopol monolithic disk polycarbonate microchips have the potential of extracting toxic dyes that could be utilized for treating wastewater.

含CuBTC-Monopol整体料的聚碳酸酯微芯片，用于染料的固相萃取。

在本研究中，通过20分钟的紫外灯辅助聚合，对2,2-二甲氧基-2-苯基苯乙酮（DMPA），甲基丙烯酸丁酯（BMA）进行了制备用于微芯片固相萃取的CuBTC-monopol整料。 ），二甲基丙烯酸乙二酯（EDMA）以及致孔溶剂系统（1-丙醇和甲醇（1：1））。在1,3,5-苯三甲酸（H ₃ BTC，10 mM）和10 mM乙酸铜（II）铜Cu（CH ₃ COO）_2的乙醇溶液的乙醇溶液中，使用CuBTC纳米晶体对所得涂层进行涂层。。本文报道了多孔CuBTC金属有机骨架的增强的提取，表征和合成研究，这些骨架采用不同的方法进行标记，包括SEM / EDAX分析，原子力显微镜（AFM）和傅立叶变换红外光谱（FT-IR）。通过回收六种有毒染料（阴离子和阳离子染料）对微芯片的性能进行了吸附剂评估。检查了各种参数（解吸和提取步骤流速，解吸溶剂的体积，样品的体积和解吸溶剂的类型），以优化使用制造的微芯片的染料提取。结果表明，CuBTC-monopol整料具有良好的渗透性，具有去除杂质的能力，并实现了高毒性染料提取回收率（83.4–99.9％）。通过计算萃取中六种染料的相对标准偏差（RSD）来评估芯片之间的再现性。批间和批内RSD介于3.8％和6.9％之间以及2.3％和4.8％之间。这些特征表明，制造的CuBTC-monopol整体式磁盘聚碳酸酯微芯片具有提取可用于处理废水的有毒染料的潜力。
