Determination of mercury in mainstream cigarette smoke with on-line oxidation coupled to atomic fluorescence spectrometry

摘要

A simple,rapid and reliable method has been developed for the determination of total mercury in mainstream cigarette smoke samples.The method used an electromagnetic induction oven as the heating source to digest sample on-line for the first time,and determined mercury by atomic fluorescence spectrometry equipped with an intermittent flow reactor.The proposed method was successfully applied to the determination of mercury in mainstream cigarette smoke samples.
