Determination of Hg and As in Cigarette Filter Components with Hydride Generation-Atomic Fluorescence Spectrometry

195 filter component samples,including tipping paper,plug wrap paper,diacetate cellulose tow,polypropylene tow,triacetin,adhesive for polypropylene fiber,polyvinyl acetate emulsion and hot melt adhesive,were determined with HG-AFS after digested with HNO₃ and H₂O₂ by heating in water bath or in a microwave oven.The results indicated that:1) the limits of detection for Hg and As were 0.1 and 1 ng/mL,respectively;their average recoveries were 93.58%-101.5% and 95.58%-102.3%,and RSDs were in the range of 1.14%-5.31% and 2.83%-6.37%,respectively;2) the contents of Hg and As in the samples were in the range of 0.002-0.051 and 0.025-0.651 mg/kg,respectively.The method is suitable for the determination of Hg and As in cigarette filter components.
