摘要

报道了一种用盐酸副罗什苯胺分光光度法快速测定普通实验室卷烟烟气中甲醛(HCHO)含量的方法,并用于评价沸石和其他多孔吸附剂对甲醛(HCHO)的去除效果。通过对氮气流和卷烟烟雾的评价,发现一些多孔吸附剂即使在严酷的实验条件下,也能在烟气中发挥良好的捕集性能,并通过ISO标准试验证明了这一点,为环保提供了一些候选材料。

Capturing formaldehyde in cigarette smoke by zeolite and porous sorbents
A spectrophotometric method of pararosaniline hydrochloride is reported for rapid determination of formaldehyde (HCHO) content in cigarette smoke in common lab and it has been used to assess the removal of HCHO by zeolites and other porous sorbents conveniently. Through the evaluation in nitrogen flow and cigarette smoke, some porous sorbents were found to exert the attractive performance in capture of HCHO in smoke even in the harsh experiment, which is proven by ISO standard test and provided some candidates for environment protection.
