Ionic liquid-modified porous polymers with large surface area and large amount of functional groups were developed and used in SPE to separate four monosaccharides. Adsorption isotherm showed that the sorbent with amino ionic liquid groups had the highest interaction with the target compounds. The mobile phase of acetonitrile/water 85:15 and 73:30 v/v can successfully separate the monosaccharides. The sorbent produced reproducible results and performed stably, demonstrating its potential applicability in the separation of extract from natural plant.
开发了具有大表面积和大量官能团的离子液体改性多孔聚合物，并将其用于 SPE 中以分离四种单糖。吸附等温线表明，具有氨基离子液体基团的吸附剂与目标化合物具有最高的相互作用。乙腈/水 85:15 和 73:30 v/v 的流动相可以成功分离单糖。所制备的吸附剂产生了可重现的结果并且表现稳定，表明其在从天然植物提取物中分离方面具有潜在的适用性。
