So far about 700 disinfection by-products have been identified but a large portion remain unknown. The focus of this research is to analyze this unknown portion to gain increased knowledge about the mixture of by-products formed in drinking water. For this purpose, a non-target approach is adopted were ultrahigh resolution mass spectrometry, specifically Fourier transform ion cyclotron resonance mass spectrometry (FT ICR MS) is used to analyze which type of by-products that are formed and adsorbable organic halogens (AOX) is used for quantitative analysis.
What I like most about doing research (except that it is very exciting) is all the people I get to meet and work together with, both at the university, at the water treatment plants and with other collaborators. In the future, I am also interested in working with drinking water issues related to challenges in developing countries.Disinfection by-products occur at low levels and need to be extracted from the water prior to analysis.
