| 摘要:本研究以(3-巯基丙基)三甲氧基硅烷和4-乙烯基苯磺酸钠为改性剂,采用两步法对纤维素滤纸进行化学改性,通过硅烷化和巯基-烯点击反应成功制备改性纤维素滤纸;利用改性纤维素滤纸化学结构中碳链的疏水作用、π-π共轭和静电相互作用, 对水相中6种卡西酮类药物进行提取和回收;将使用后的改性纤维素滤纸利用不同的洗脱溶剂进行处理,并通过高效液相色谱-三重四极杆质谱联用仪对洗脱液进行检测和分析。结果表明,在环境pH值=6.0时,改性纤维素滤纸对6种卡西酮类药物的回收效果最佳,回收率在71.5%~107.7%之间;最佳洗脱溶剂为体积分数3%的氨水/甲醇溶液;此外,改性纤维素滤纸在重复使用5次后,依然可以保持较高的回收率。 |
| Abstract:A two-step preparation method was adopted to chemically modify cellulose filter paper. (3-mercaptopropyl)trimethoxysilane and sodium 4-vinylbenzenesulfonate were used as modifiers. The chemically modified cellulose filter paper (CMCFP) was successfully prepared through silanization and thiol-ene click reaction. The CMCFP was used to extract and recover six synthetic cathinone analytes in aqueous solution by taking advantage of its hydrophobic interaction, π-π interaction, and electrostatic interaction. After extraction, the used CMCFP was treated with different elution solvents, and the eluates were detected and analyzed using high-performance liquid chromatography coupled with triple quadrupole mass spectrometry. The results showed that at an environmental pH value of 6.0, the CMCFP achieved optimal recovery efficiency for the six synthetic cathinone analytes, with recovery rates ranging between 71.5% and 107.7%. The most effective elution solvent was found to be ammonia/methanol solution with fraction volumique of 3%. Furthermore, the CMCFP maintained high recovery performance even after five consecutive uses. |
