Abstract | Compound specific isotope analysis (CSIA)
has been used to explore the degradation pathways of
di-(2-ethylhexyl)-phthalate (DEHP) in photosensitization experiments
with H2O2, TiO2, Fe(III) and PMS. The reaction kinetics could be described by first order rate constants [k (h−1)]. The highest degradation rates of DEHP were observed in UV/TiO2 catalyzed reactions. Carbon isotope fractionation factors (εC) and metabolite patterns were examined to analyze the radical reaction. Similar carbon isotope fractionation factors have been found in experiments dominated by ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() |
