Dimethylamine　(DMA)　and　N,N-dimethylformamide　(DMF)　are　typical　N-VOCs　exhausted　from　manufacturing　factories.　In　the　present　study,　the　behavior　of　non-thermal　plasma　(NTP)　was　systematically　investigated　for　removal　of　gas-phase　DMA　and　DMF　in　a　link　tooth　wheel-cylinder　plasma　reactor.　Experimental　results　show　that　DMA　is　much　easier　to　be　decomposed　by　NTP　than　DMF.　On　the　other　hand,　coexisting　DMF　has　no　effect　on　DMA　conversion　while　DMF　conversion　is　significantly　promoted　by　the　addition　of　DMA.　It　is　also　found　that　regardless　of　initial　gas　compositions　as　well　as　DMA　and　DMF　concentration,　COx　selectivity　increased　monotonously　with　increasing　ED.　But　COx　selectivity　of　100%　cannot　be　obtained　even　with　ED　higher　than　70　J　L-1,　indicating　the　formation　of　organic　intermediates　during　DMA　and　DMF　decomposition.　Based　on　organic　products　analysis　with　GC-MS　and　molecule　optimization　results　with　density　functional　theory　calculation,　possible　mechanisms　on　DMA　and　DMF　degradation　were　proposed.　On　the　other　hand,　the　organic　products　from　DMA　and　DMF　decomposition　by　NTP　were　found　to　have　great　solubility　and　high　biodegradability.　Thus,　NTP　enhanced　absorption/biological　method　is　suggested　for　complete　removal　of　DMA　and　DMF.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
