Abstract

The elution behaviour of polycyclic aromatic hydrocarbons (PAHs, 13 of the 16 U.S. Environmental Protection Agency priority pollutants and peropyrene types) was studied on several chemically bonded stationary phases (octadecylsilicas, di- and triphenylsilicas, naphthylethylsilica and pyrenylethylsilica) under reversed-phase conditions. The results showed that the elution order of peropyrene-type PAHs is highly dependent on the degree of planarity of the solute and on the orderlines of the bonded phases, whereas no definite differences were found in the retention behaviour of the 13 small PAHs on various stationary phases. The characteristics of all the stationary phases could be classified by statistical cluster analysis.

摘要

在反相条件下，研究了多环芳烃（PAHs，美国环境保护局优先污染物中的16种中有13种以及苝系多环芳烃）在几种化学键合固定相（十八烷基硅胶、二苯基和三苯基硅胶、萘基乙基硅胶和芘基乙基硅胶）上的洗脱行为。结果表明，苝系多环芳烃的洗脱顺序高度依赖于溶质的平面度和键合相的有序度，而13种小分子多环芳烃在不同固定相上的保留行为未发现明显差异。所有固定相的特性可通过统计聚类分析进行分类。
