Browse all Theses and Dissertations

The purpose of the research was to design a method using high-performance liquid chromatography (HPLC) that would separate the sixteen polycyclic aromatic hydrocarbons (PAHs) designated by Environmental Protection Agency (EPA) as priority pollutants on two different kinds of polystyrene (PS) in the reversed phase. One was a zirconia-based column coated with polystyrene. The other was a polystyrene divinylbenzene (PS-DVB) column. The idea behind using these columns was to take advantage of extreme retention of PAHs by these columns by using high temperatures or temperature programming in order to reduce the amount of organic modifier in the mobile phases to perform …
