Abstract
A relatively simple procedure for measuring H2SO4 in auto exhaust will be presented. The system is compatible with the Federal constant volume sampler (CVS unit). The time required to get sufficient sample for titration is 15-30 min. Values on sulfates in exhaust with a catalyst car and a noncatalyst car agree well with literature data obtained by dilution tube and filtration techniques.
摘要
将介绍一种相对简单的测量汽车尾气中硫酸的方法。该系统与联邦定容采样器（CVS装置）兼容。获取足够用于滴定的样品所需时间为15 - 30分钟。装有催化器的汽车和未装催化器的汽车尾气中硫酸盐的测量值与通过稀释管和过滤技术获得的文献数据吻合良好。
