   Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. LÄS MER

3. 2. Development and application of a solidphase extraction method for simultaneousdetermination of PAHs, oxy-PAHs andazaarenes in water samples

   Master-uppsats, Kemiska institutionen

   Författare :Yu Wang; [2012]
   Nyckelord :;

   Sammanfattning : In this study, a solid phase extraction (SPE) method was developed that can be used to extract a wide range of polycyclic aromatic compounds (PACs), including polycyclic aromatic hydrocarbons (PAHs), oxygenated PAHs (oxy-PAHs) and azaarenes, from water samples. Three commercially available SPE materials, i.e. LÄS MER
