2. Sorption and transformation of polar pharmaceuticals during wastewater treatment studied by hollow fiber liquid phase microextraction
Sammanfattning : This thesis addresses the application of hollow fiber liquid phase microextraction as a simple, efficient and environmentally friendly tool to study the fate of four common anti-inflammatory drugs (ketoprofen, naproxen, diclofenac and ibuprofen) during wastewater treatment. Initial experiments verified that this technique is applicable on aqueous as well as suspensions of solid samples, thus greatly simplifying the sample preparation. LÄS MER
