文摘
- •
A novel photoelectro-peroxone (PEP) process was developed by coupling ozonation, UV photolysis, and electrolysis processes.
- •
H2O2 is electro-generated from O2 in sparged O2 and O3 gas mixture (ozonizer effluent).
- •
The in-situ generated H2O2 then undergoes UV-induced photolysis or reacts with O3 to yield
OH.- •
The PEP process can produce more
OH than UV/O3 and electro-peroxone (EP) processes.- •
PEP mineralizes substituted benzenes much more rapidly and energy-efficiently than UV/O3 and EP processes.
