卷烟主流烟气中As、Cd、Pb的滤嘴截留效率测定

摘要

采用微波消解-ICP-MS测定醋酸纤维滤嘴、活性碳复合滤嘴、波纹滤嘴和纸质复合滤嘴对主流烟气中As、Cd、Pb的截留效率（FE）。结果表明：滤嘴长度的增加，截留效率均有不同程度的增加。不同类型滤嘴对3种不同元素的截留效率具有选择性，截留效率大小顺序为As：FE纸质＞FE波纹＞FE醋纤＞FE活性碳，Cd：FE活性碳＞FE纸质＞FE波纹＞FE醋纤，Pb：FE纸质＞FE醋纤＞FE波纹＞FE活性碳。%Filter retain efficiencies of As, Cd and Pb in mainstream cigarette smoke were determined by microwave digestion-ICP-MS using different sizes and types of cigarettefilters. Results showed thatfilter retain efficiencies of all three elements increased with the increase offilter length. Filter retain efficiencies of differentfilter types, i.e. cellulose acetate (CA), active carbon combined with CA(CCA), groove CA(GCA) and paper retain with CA (PCA)filters, of three elements showed a trend of As:FEPCA>FEGCA>FECA>FECCA, Cd:FECCA>FEPCA>FEGCA>FECA,Pb:FEPCA>FECA>FEGCA>FECCA.
