Abstract:Objective] The research' aimed to establish a new method for the determination of arsenic content in cigarette paper by atomic fluorescence spectrometry with microwave ashing.Method] The samples of cigarette paper were treated by microwave ashing.And then arsenic content was determined by using atomic fluorescence spectrometry.Result] Arsenic in the range of 0.2-20 μg/L had a good linear relationship with the fluorescence intensity.Its regression equation was If=286 C(μg/L)+ 2.68(r=0.999 5).The recovery rate of this method was 95.4%-97.0% and the detection limit was 0.04 μg/L.Conclusion] The determination of arsenic content in cigarette paper by atomic fluorescence spectrometry with microwave ashing had high sensitivity,low detection limit,good precision and high recovery rate and the method can meet the determination demands of trace arsenic in cigarette paper.
Keywords:Microwave ashing  Cigarette paper  Arsenic  Atomice fluorescence spectrometry
