| Abstract: | A denuder-based method for sampling and separating ga seous and particulate mercury in the air was described.The comparison results fo r denuder and a traditional filtration method were presented.At flow rate of 1Lmin-1,the collection efficiency of a denuder 600mm in length was over 99 % for gaseous mercury. |
