Ion Mobility Spectrometry (IMS)

Ion mobility spectrometry, originally used to detect gaseous pollutants of organic contaminants e.g. chemical warfare agents, explosives and illegal drugs in air is a promising technique combined with a suitable sample introduction system also for analyzing aqueous samples. The interest in simple, inexpensive and fast techniques, which can be used for online monitoring, has grown also in terms of water analysis in recent years.

Advanced Oxidation Processes (AOP)

  • Investigation of fundamental mechanisms in oxidative water treatment processes (e.g., ozonation, Fenton, chlorine dioxide, photo-oxidation UV, UV/H2O2 and UV/S2O82)
  • Studies on reaction pathways in pollutant degradation and by-product formation
