About Stefan Karlsson

Stefan Karlsson is professor in chemistry and presently also the vice dean of the Faculty of business, science and technology.

My research concerns the relationships between chemical state/speciation of trace metals in relationship to their movement in the hydrogeosphere and technical systems, but also their interactions with organisms. This includes field studies of the hydrogeochemistry behind spatial and temporal processes in boreal environments, including those that are polluted from historical mining. More applied science is directed towards the recovery of valuable elements from different kind of waste such as mining waste, slag from steel production, sewage sludge and ashes from different sources. Other applications are remediation of metal contaminated soil and treatment of contaminated water with solid waste.

Since my research is focussing on elucidating reaction mechanisms, I am also developing analytical methods for qualitative and quantitative analysis of metal species. Among these are HPLC, ICP-MS, ICP-MSMS, ion-exchange chromatography and capillary electrophoresis. In recent years I have also been involved in application development for MP-AES (micro plasma atomic emission spectroscopy.
