Evaluation of the removal efficiency of perfluoroalkyl substances in drinking water (Master)

The quality of tap water is considered to be high. Recently, however, several water sources had to be restricted or even shut down because of the occurrence of perfluoroalkyl substances (PFASs), such as perfluorooctane sulfonate (PFOS) in drinking water. PFASs have received increasing public attention due to their persistence, bioaccumulative potential, and toxicity. However, only a few data are available on the removal efficiency of PFASs in drinking water treatment plants. The student performing this master thesis work will evaluate different water treatment techniques in pilot-scale with respect to removal efficiency of PFASs. The experiments and chemical analysis will be performed by the student. The student should have laboratory experience and be interested in analytical chemistry.
