制备了星状介孔二氧化硅纳米颗粒（SMSNs）的无机-有机杂化整体石。采用二元溶剂、深共晶溶剂和室温离子液体制备的smsn掺杂聚甲基丙烯酸丁酯-共乙二醇二甲基丙烯酸酯单体结构均匀，柱渗透性好。对SMSN含量、交联单体含量、二元溶剂组分等制备参数进行了系统的研究。采用场发射扫描电镜、透射电镜、区域扫描能谱和氮吸附等方法对优化后的单片进行了表征。采用毛细管电色谱法（CEC）分离烷基苯、苯胺、萘和酚四类分析物，考察柱性能。所有分析物的基线分离获得柱效率高达266,000板m−1。通过分离多环芳烃（PAHs）、非甾体抗炎药（NSAIDs）和羟基苯甲酸异构体的混合物，进一步详细研究了所得单体的性能。与相应的无smn单体相比，CEC性能提高了约6倍。该毛细管还成功提取了多环芳烃和喹诺酮类化合物。将该材料应用于固相微萃取法提取荧光蒽时，对湖水等复杂样品的萃取效率达到20.2%。摘要以星形介孔二氧化硅纳米颗粒为载体，制备了聚甲基丙烯酸丁酯-二甲基丙烯酸乙二醇酯整体体。它证明了柱效率高达266,000板m−1in毛细管电色谱和能力作为固相微萃取有机小分子具有良好的柱渗透性。
An inorganic-organic hybrid monolith incorporated with stellated mesoporous silica nanoparticles (SMSNs) was prepared. Using binary solvents, deep eutectic solvents and room temperature ionic liquids, an SMSN-incorporated poly(butyl methacrylate-co-ethylene glycol dimethacrylate) monolith demonstrated uniform structure with good column permeability. A systematic investigation of preparation parameter was performed, including SMSN content, crosslinking monomer content, and the component of binary solvent. The optimized monoliths were characterized by field emission scanning electron microscopy, transmission electron microscopy, area scanning energy dispersive spectrometry, and nitrogen adsorption. Column performance was tested by separating four groups of analytes (alkylbenzenes, anilines, naphthalenes and phenols) by capillary electrochromatography (CEC). Baseline separation of all analytes was obtained with column efficiencies of up to 266,000 plates m−1. The performance of the resulting monolith was further investigated in detail by separating mixtures of polycyclic aromatic hydrocarbons (PAHs), nonsteroidal antiinflammatory drugs (NSAIDs), and hydroxybenzoic acid isomers. Compared with the corresponding SMSN-free monolith, the CEC performance was improved by about six times. Successful extraction of PAHs and quinolones (QNs) were also performed using this capillary. Improved extraction efficiency (20.2%) for complex samples, lake water, was also found when the material was applied to solid phase microextraction of fluoranthene.Graphical abstractA poly(butyl methacrylate-co-ethylene glycol dimethacrylate) monolith incorporated with stellated mesoporous silica nanoparticles was prepared. It demonstrated column efficiency up to 266,000 plates m−1in capillary electrochromatography and ability as solid phase microextraction for organic small molecules with good column permeability.
