摘要

通过表面组装(1)和一步硅烷固定化(2)制备了两个含有锚定蒽基甲胺基团的功能化介孔二氧化硅(SiO2-Ant)样品。这两种吸附剂都可以归因于蒽基团负载量约为15-33%的双峰平衡疏水亲水吸附剂。吸附剂已用于从有机溶剂(乙腈、丙酮和庚烷)和脂质模型溶液(肉豆蔻酸和植物油)中固相萃取(SPE)蒽。将获得的结果与商业C18 SPE柱进行比较。C18柱从含水介质(乙腈/水,1/1)中回收蒽,而SiO2-Ant柱在从非极性溶剂(庚烷)中提取蒽方面效率高得多。脂质大组分如肉豆蔻酸和植物油不会降低模型多环芳烃(PAH)在SiO2-Ant上的动态吸附能力和回收率。结果表明,与分析物的π-π堆积相互作用决定了SiO2-Ant对蒽的选择性。这使得SiO2-Ant对于高脂质含量物体(如植物油)的PAHs的选择性预富集具有吸引力。

Mesoporous Silica With Covalently Immobilized Anthracene As Adsorbent For SPE Recovery Of PAHs Pollutants From Highly Lipidic Solutions
Two samples of functionalized mesoporous silica containing anchored anthrylmethylamine groups (SiO2-Ant) have been prepared by surface assembling (1) and one step silane immobilization (2). Both adsorbents can be attributed to bimodal balanced hydrophobic-hydrophilic adsorbents with loading of anthracene groups about 15-33 %. The adsorbents have been used for solid-phase extraction (SPE) of anthracene from organic solvents (acetonitrile, acetone and heptane) and model solutions of lipids (myristic acid and vegetable oil). The obtained results were compared with commercial C18 SPE cartridge. While C18 cartridge recovers anthracene from water-containing media (acetonitrile/water, 1/1), SiO2-Ant cartridges much more efficient in extraction of anthracene from non-polar solvent (heptane). Lipids macrocomponents such as myristic acid and vegetable oil do not decrease the dynamic adsorption capacity and recovery of the model polycyclic aromatic hydrocarbon (PAH) on SiO2-Ant. It was demonstrated that π-π stacking interaction with the analyte determine the selectivity of SiO2-Ant towards of anthracene. This makes SiO2-Ant attractive for selective preconcentration of PAHs from high lipid content objects, such as vegetable oils.
