    Abstract: Chlorine and hydrogen sulfide contamination in a local atmosphere is removed by drafting a ventilation flow stream of the contaminated atmosphere over an activated carbon adsorber bed. Saturation of the adsorber bed by adsorbed contaminant occurs as a progressive front advancing along the flow stream direction. One or more chlorine and hydrogen sulfide sensitive monitors signal passage of the saturation front at designated bed depth points. Each monitor is exposed to a small air sample flow from the bed at the respectively designated point. Each sample flow is directed serially over two reactive paper filters: the first being impregnated with 0-toluidine to remove Cl.sub.2 and the second being in impregnated with lead acetate to remove H.sub.2 S. Both filters respond to the respective compounds with a color change. Monitor construction and assembly places both filters side-by-side behind transparent chamber windows for manual observation of the color change without disassembly of the monitor unit.

    Abstract translation: 通过在活性炭吸附床上起草污染气氛的通风流来除去局部气氛中的氯和硫化氢污染物。 通过吸附的污染物吸附床的饱和度是沿着流动流方向前进的前进方向发生的。 一个或多个氯和硫化氢敏感监视器在指定的床深度点上通知饱和度前沿。 每个监视器在分别指定的点处暴露于来自床的小空气样本流。 每个样品流均匀地排列在两个反应性纸过滤器上:第一个用O-甲苯胺浸渍以除去Cl 2,第二个用乙酸铅浸渍以除去H 2 S。 两个过滤器都对颜色变化的各个化合物进行响应。 显示器构造和组装将两个过滤器并排放置在透明室窗后面,以手动观察颜色变化,而不会拆卸显示器单元。
