摘要
香烟烟气中含有相当数量的羰基化合物,它们能致癌或协同致癌。本文采用2.4一二硝基苯肼法,对香烟主流烟气中的羰基化合物含量进行测定获得成功。该方法的线性范围为4.28×10^(-7)～1.54×10^(-4)mol/L,(r=0.9978),最低检出限为4.28×10^(-7)mol/L;样本加标回收率和日间变异系数分别为91.5％～107.8％(n=12)和4.1％(n=7)。已测定市售有滤嘴与无滤嘴“大重九”牌香烟(昆明),过滤嘴仅滤除去羰基化合物的23％。
A colorimetric assay by the 2.4-dinitrophenylhydrazine for carbonyl compounds in the cigarette smoke has been developed. The linear range was 4.28×10^(-7)～1.54×10^(-4)mol/L (r=0.9978) The recovery and coefficient variation were 91.52～107.8% (n=12) and 4.1% (n=7), respectively, This method was used for the determination of carbonyl compounds in the main stream smoke of 'Da chong jiu' cigarette (Kun ming).
