文摘

AP photodegradation (UV-H2O2/TiO2) was studied in a spinning disc reactor. Synergism between individual processes and the overall (UV/H2O2/TiO2) was 4.2%. The TiO2 disc can be regenerated up to 10 cycles with no loss in efficiency. The maximum rate constant was 6.9·10−4 s−1 with no mass transfer limitation. After intermediates identification, a mechanism is proposed for AP photodegradation.
