Carbon disulfide (CS 2 ), a typical odorous organic sulfur compound, has adverse effects on human health and is a potential threat to the environment. In the present study, CS 2 conversion in air by non-thermal plasma (NTP) was systematically investigated using a link tooth wheel-cylinder plasma reactor energized by a DC power supply. The results show that corona discharge is effective in removing CS 2 . The CS 2 conversion increases with the increase of specific input energy (SIE). Both short-living (e.g. O, OH radicals) and long-living species contribute to the CS 2 conversion, but the short-living species play a more important role. Both gaseous and solid products are formed during the conversion of CS 2 . Gaseous products mainly include CO, CO 2 , OCS, SO 2 , SO 3 and H 2 SO 4 . The yields of CO and CO 2 increase, the yields of OCS and SO 2 follow bell curves while the sum yield of SO 3 and H 2 SO 4 remains constant as SIE increases. The solid products, consisting of CO 3 2− , SO 4 2− and possible polymeric sulfur, deposit on the inner wall and electrodes of the plasma reactor.
