TY - CONF A1 - Frenzel, Olivia A1 - Piechotta, Christian T1 - Identification of Metabolites and Transformation Products of Bisphenols N2 - Bisphenol A (BPA) is used in Polycarbonate (PC), polyacrylic resins (PAR), polysulfones (PSU), epoxy resins (ER), and polyetherimides (PEI). It is also applied in recycled polyvinyl chloride (PVC). Many outdoor applications are made from these BPA-based materials which are exposed to a variety of environmental impacts, like temperature, global radiation, rain, and others. This could lead to damaging and aging of the material which might cause leaching or migration of pollutants into the environment. Understanding the fate and behavior of the released pollutants is very important. Therefore, different transformation products (TP) will be generated and analyzed: 1. To investigate the behavior of various bisphenols in wastewater treatment plants, possible technical TP are generated by UV irradiation. Simulation of Industrial wastewater treatment is realized by using the Fenton reaction, an advanced oxidation process. 2. To study the transformation of bisphenols in surface waters, global radiation will be simulated by using UVA lamps. 3. To simulate phase 1 metabolism, an electrochemical cell coupled to a mass selective detector is applied. The analysis of metabolites and TP are achieved by a variety of gas and liquid chromatographic techniques coupled with mass spectrometry. The elucidation of the exact structure of the obtained TP and metabolites are done by 1H- and/or 13C-NMR experiments.
