Being　emitted　into　the　atmosphere,　toluene　as　one　of　the　important　volatile　organic　compounds　would　impact　the　air　quality　and　degrading　our　living　environment　As　a　result,　emission　of　toluene　has　caused　much　public　concern　from　the　view　point　of　protection　of　human　health　and　environment.　With　a　view　to　broader　the　industrial　application　improving　of　removal　efficiency　remains　a　primary　work.　Basing　on　the　combination　of　corona　plasma　and　dielectric　barrier　discharge　in　the　high　frequency　power　output,　this　paper　discussed　the　influence　on　the　toluene　gas　removal　efficiency　experimentally,　which　was　affected　by　applied　voltage,　frequency,　materials　of　reactor,　as　well　as　the　diameter　of　electrode.　Experimental　results　show　that　the　removal　rate　will　be　increased　by　applying　high　voltage.　The　removal　efficiency　of　toluene　gas　will　reach　as　high　as　96.25%　when　frequency　is　6　kHz　and　the　voltage　is　15.4　kV.　In　addition,　three　kinds　of　materials　which　having　different　dielectric　constants,　ie.　the　common　ceramics,　99%　ceramics　and　acrylics　were　discussed.　The　experimental　data　show　that　material　differences　have　little　impact　on　the　removal　efficiency　under　low　voltage　condition.　While　under　high　voltage　condition,　the　removal　efficiency　rate　of　the　99%　ceramics　is　the　highest,　followed　by　the　common　ceramics,　and　the　acrylics　is　the　third.　This　paper　also　did　research　on　the　removal　effect　by　applying　different　size　of　electrode　diameters　of　1.00　mm,　1.65　mm　and　2.00　mm.　The　data　show　that　the　removal　efficiency　with　thicker　electrode　is　higher　than　the　thinner　one.　However,　the　high　voltage　applied　is　a　precondition.
