  Microbial biodegradation and metabolite toxicity of three pyridinium-based cation ionic liquids

  摘要：

  融合绿色化学、生态毒理学和生态学等学科，开发环境友好型工业化学品是一项重大的合作挑战。要应对这一挑战，就必须扩展已有的信息丰富的标准毒性和生物降解性检测方法，使其包括有关污染物在环境中的潜在持久性和生物转化的更多信息。离子液体（ILs）的开发提供了一个理想而积极的测试系统，可利用学术上有趣且与工业相关的绿色化学原型来确定环境影响的多个级别。在这项研究中，我们调查了活性污泥微生物群落对三种离子液体（1-丁基-3-甲基溴化吡啶鎓、1-己基-3-甲基溴化吡啶鎓和 1-辛基-3-甲基溴化吡啶鎓）的生物降解性。我们确定这三种 IL 都可以完全矿化，但只有辛基取代的阳离子可以归类为 "易于生物降解"。我们使用反相高效液相色谱/质谱法和 MS/MS 法直接检测了 IL 的生物降解产物，并确定了几种独特的初步降解产物。最后，我们确定，与初始化合物相比，IL 生物降解产物对标准水生测试生物大型蚤的毒性更低，这表明在水生环境中的生物降解会降低与初始化合物相关的毒性危害。本研究提供了有关吡啶鎓惰性生物降解的更多信息，并为今后惰性生物降解的设计和研究提供了指导。

  Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution. This study shows that IL-generated porous morphology alone is not enough to provide effective extraction media: careful choice of the organic polymer and the precursor with close sol-gel reactivity must be made to ensure effective chemical bonding of the organic polymer to the created sol-gel material to be able to provide the desired sorbent characteristics.
