Abstract
Two methods that use LiOH to selectively remove CO2 from ambient whole air samples were found to be capable of decreasing CO2 in ambient air samples by 4 orders of magnitude, with only a minimal effect on their volatile organic compound (VOC) content. According to VOC speciation findings, aldehydes generally suffered the greatest loss during CO2 removal, while hydrocarbons were virtually unaffected.
