摘要
基于当携带有分析物的β-环糊精穿过1-金刚烷酸溶液区带时,分析物被1-金刚烷酸置换下来后经分配进入SDS胶束而使分析物迁移速度降低的机理,建立了一种样品堆积MEKC富集分离方法,使BPA和三种烷基苯酚得到了10倍左右的富集。另外,采用此样品堆积MEKC富集分离测定方法在实际湖水样中检测到了两种未知化合物。
A stacking technique was developed. It was based on the reduction of migrating speed of analytes when the analytes was displaced out the cavity of β-cyclodextrin by 1-adamantanecarboxylate and partitioned into the SDS micelle. The stacking technique was able to concentrate BPA and the three alkylphenols by about 10-fold. In addition, two unidentified compounds were detected in a real lake water sample by using MEKC with the stacking technique.
