摘要毛细管电色谱(CEC)是综合现代最新分离技术高效液相色谱(HPLC)和毛细管电泳(CE)的优势而发展起来的一种高效微分离技术,它具有高效性、高选择性、高分辨率及快速分离的优点。随着CEC柱制备技术、分离机制、仪器设备的不断发展和完善,CEC已经在分析领域中引起广泛关注,并在有机小分子分离分析、环境分析、药物分析和生化分析等方面得到应用。本文主要利用具有双功能基团pAS上的氨基先在柱外以酰胺键结合GO,再将此产物(pAS-GO)引入毛细管柱中同与St和DVB聚合获得一种新型的含氧化石墨烯功能基团的聚苯乙烯整体柱(GO@PS-DVB),该整体柱成功的分离了酸性、碱性和中性目标物,并探讨了整体柱分离机理。72783
Abstract: Capillary electrochromatography (CE) is a combination of the modern new separation technology, which used of the advantages of high-performance liquid chromatography (HPLC) and capillary electrophoresis(CE)。 As a kind of efficient separation technology, it has high efficiency, high selectivity, high resolution, and the advantage of rapid separation。As CEC column preparation technology, separation mechanism, instrument and equipment of continuous development and improvement of CEC has caused wide public concern in the field of analysis, and in the organic small molecular separation analysis, environmental analysis and drug analysis has been applied and biochemical analysis, etc。 In this paper, we use with double functional groups outside the amino in the first column on the pAS in amide bond GO,then this product (pAS - GO) in the introduction of capillary column with St and DVB polymerization to obtain a new type of compound GO@PS-DVB。The whole column succeeded in the separation of acidic, alkaline and neutral targets, and discusses the separation principle of monolithic column。
