Plasma Degradation of Dibromophenols and Interpretation by Molecular Orbital Theory

Dielectric barrier discharge was operated in the liquid-gas boundary and applied to the degradation of Dibromophenol (DBP). The brominated aromatic compound show acute toxicity to aqueous living and, occasionally, carcinogenic and hormone-disruptive effect for human. The plasma degradation provides the advanced oxidation process by charged species, anion as well as neutral radicals. Plasma-degradation with the anion-exchange successfully worked and the controlled the production of BrO3− by NO3− . Interpretation of the observed difference in the resistance is interpreted using the Molecular Orbital Theory.
