My primary research interest is the assessment of activated carbon fibers (ACFs) for improved design of respirators. In my previous research prior to coming to East Carolina University (ECU), I investigated the potential of different ACF types to serve as alternative adsorbents to granular activated carbon (GAC) in respirators for protection against airborne toluene. This research has demonstrated that ACF makes a good candidate for developing thinner, lighter and more efficient respirators. My ultimate research goal is to design and test the actual respirator using different types of ACF as the adsorbent. I have found that certain ACF types and dimensions resulted to acceptable pressure drop across ACF respirator cartridges and promising adsorption characteristics (i.e., breakthrough, adsorption capacity) of ACF respirator cartridges for toluene and, potentially, other volatile organic compounds. My further investigations will involve the effects of humidity and respiration rate on ACF adsorption for toluene and other volatile organic compounds.
