Abstract
In the conducted research, a methodology for the determination of three hydroxy derivatives of polycyclic aromatic hydrocarbons (OH-PAHs) (1-hydroxypyrene, 2-hydroxyfluorene, 2-hydroxynaphthalene) was developed by using a liquid chromatography equipped with a spectrophotometric detector and a Kinetex C18 column. Solid-phase extraction efficiency tests were carried out for cartridges filled with various sorbents. The column filled with silica gel modified with octadecyl groups showed the highest recovery (74%–92%). The last stage of the research was to assess the stability of selected OH-PAHs in order to determine whether any transformation is possible during their transport to the environment from the wastewater treatment plants. It was decided to simulate the conditions in the sewage system during the summer and winter periods by conducting an experiment at a temperature of 22°C and 4°C. In addition, the analyses were carried out in parallel on two matrices with the addition of analytes standards: deionized water and real wastewater. The stability test that was performed demonstrated that within 72 h, regardless of the prevailing conditions, all analysed OH-PAHs remain stable, which means that no hydraulic retention occurs in the analysed period. Furthermore, no differences between the used matrices were noticed, which proves that the chemical diversity of wastewater does not accelerate their degradation in the sewage system.
