Removal of p-chlorophenol in mist by DC corona discharge plasma.

Highlights: [•] The removal of 4-CP and TOC improves as input power increases. [•] 4-Chlorocatechol is the dominating hydroxylated intermediate. [•] Most of the chlorine atoms are released from the removed 4-CP to form Cl−. [•] Yields of ring-opening and ring-containing products take up less than 50% and 1%. [•] Both short-living and long-living plasma species contribute to 4-CP degradation. [ABSTRACT FROM AUTHOR]
