| Abstract: | Effects of some factors were studied on the degradation of phenol in aqueous solution with pulsed high voltage corona discharge plasma. The degradation of phenol could be raised considerably by increasing the peak voltage and discharge frequency and by prolonging the discharge time. The existence of radical scavenger such as n butanol and buffer such as borate could decrease the degradation of phenol. The maximum degradation of 100mg·L-1 phenol solution was 67 3% after discharging for 180minutes. The TOC of wastewater decreased by 83 8% when discharge time was 420minutes. |
