Abstract
This research is part of a program to study the feasibility of using a modified mode of electrostatic precipitation to remove polar gaseous trace contaminants from manned space-cabin atmospheres. A cell was developed for the removal of polar contaminant molecules from a 100 ml/min air inflow at part-per-million concentration levels of the contaminant. The operating principle of this cell is as follows: Positive lithium ions are thermionically generated and injected into the contaminated air stream. Ionic reaction products are collected at a set of porous metal collection electrodes. These electrodes are air-eluted. They are situated at the bottoms of slot-shaped wells to minimize escape of the collected contaminant molecules through diffusion. A measured efficiency of 20% for removal of acetone at a concentration of 1 ppm in dry air was finally achieved with this cell after considerable development work on the apparatus. This result is tentative pending further confirmatory experiments.
