摘　　要：分别采用10%盐酸+5%硝酸、10%盐酸和剑桥滤片捕集主流烟气中的砷,捕集后10%盐酸+5%硝酸和10%盐酸用水浴沸腾加热3 h,剑桥滤片用10%盐酸+5%硝酸超声浸提1h,处理后的样品用原子荧光光谱法检测砷,3种方法的平均回收率分别为94.3%、99.8%、96.3%,3种方法捕集主流烟气中砷的相对标准偏差在6.90%—9.86%之间,同时发现硝酸浓度大于等于8%时,对测定砷产生负效应,其中采用10%盐酸+5%硝酸对测定砷无负效应。The methods for trapping arsenic in cigarette mainstream smoke were established by 10% hydrochloric acid＋5% nitric acids,10% hydrochloric acid and in the Cambridge filter leaf.10% hydrochloric acid ＋5% nitric acids and 10% hydrochloric acid were heated for 3h with the water bath ebullition after trapping,and 10% hydrochloric acid ＋5% nitric acids for the Cambridge filter leaf was extracted for 1h by supersonic soaks.Then arsenic in the processing samples were detected by atomic fluorescence spectrometry,and the average recoveries for three methods were 94.3%,99.8%,96.3%,respectively,while RSD of arsenic in cigarette mainstream smoke was in the range of 6.90%—9.86%,when the concentration of nitric acid was great than or equal to 8%,the determination of arsenic had negative effect,but 10% hydrochloric acid ＋5% nitric acids did not have negative effect on detection of arsenic.
