摘　　要：采用微型被动采样器,以N-(9-Acridinyl)-maleimide(NAM)为荧光试剂,建立了微流动注射荧光检测测定个人二氧化硫暴露量的方法.被收集的二氧化硫作为亚硫酸根离子和NAM在微流路中反应并被检测,测定结果同离子色谱法进行了比较,该法检测中消耗的试剂量极少,几乎不会对环境造成任何污染,是一种环境友好的分析方法.By using mini-passive sampler and fluorescence reagent N-（9-Acridinyl）-maleimide, a micro flow injection/fluorescence detection method for determination of sulfur dioxide in air was developed. The sulfur dioxide was absorbed as sulfite, which reacted with NAM,and the fluorescence was detected in the microchannel. The analysis results were satisfied by comparing with the results of ion chromatography method. With lower consumption of reagents, it is an environment friendly method.
