Furthermore, we examined simultaneous variations of ozone and its precursors during 2015 Grand Military Parade and 2014 APEC meeting and evaluated the performances of different emission-reduction measures during the two specific events.
Breakthrough curves were obtained experimentally and the system was evaluated with regards to column operation time, efficiency and productivity as functions of simultaneous variations of superficial velocity (vz) and bed height (L) using a central composite rotatable design (CCRD).
