制备了新型高效棒状(甲基丙烯酸-苯乙烯-二乙烯基苯)共聚物高效液相色谱柱,扫描电镜显示其具有大孔网络结构,从而表现出良好的通透性.以乙腈-水(90/10,V/V)为流动相,在流速为2.0mL/min下,柱压仅为2.5MPa.采用等度淋洗实现了多环芳烃及芳香酸的分离.该方法简便且重现性好,具有很好的发展潜力. A novel highly efficient rod-shaped (methacrylic acid-styrene-divinylbenzene) copolymer high performance liquid chromatography column was prepared, which showed a macroporous network structure by scanning electron microscopy to show good permeability. 90/10, V / V) as the mobile phase at a flow rate of 2.0 mL / min and a column pressure of only 2.5 MPa.The separation of PAHs and aromatic acids was achieved by isocratic leaching.The method was simple and reproducible Good sex, with good potential for development.
