Investigation of the synergistic effects for p-nitrophenol mineralization by a combined process of ozonation and electrolysis using a boron-doped diamond anode

- Combining electrolysis with ozonation greatly enhances nitrophenol mineralization.
- O3 can rapidly degrade nitrophenol to carboxylic acids in the bulk solution.
- Carboxylic acids can be mineralized by OH generated from multiple sources in the electrolysis-O3 process.
- Electrolysis and ozonation can compensate for each other's weakness on pollutant degradation.
