Abstract—Degradation of phenol by streamer corona plasma in Prebreakdown phenomena in water with and without gas
aqueous solution with suspended TiO2 was conducted. The bubbling were first investigated for point-plane geometries
experimental results present that the addition amount, the crystal using high-voltage pulses [7], it was found that ozone was
size and structure of TiO2 influenced the phenol degradation. In produced and anthraquinone was discolored when the
this paper phenol degradation increased with the addition discharge was operated with a gas flow through the nozzle
amount of TiO2 in the range of 0- g/L; the highest degradation anode. From then on, pulse discharge plasma has been
rate of phenol was obtained when Degussa P25 (75% anatase and extensively used to anic wastewater containing phenol
25% rutile) was used rather than A30 and A50 (anatase); 95% of [8-12]. Lukes et al [11] found phenol degradation was mainly
