title = "Effect of surface oxygen groups on the irreversible adsorption of organic vapors",
abstract = "The effect of activated carbon's oxygen functional groups on the irreversible adsorption of organic vapors emitted from automotive painting operations was investigated. Microporous beaded activated carbon (BAC) was treated with H2 to remove oxygen groups or treated with nitric acid to add acidic oxygen groups. No significant change in mass balance cumulative heel was observed. Stronger physisorption was noted for heat-treated and H2-treated BAC. A combination of weak physisorption and strong chemisorptions resulted to heel formation on nitric acid-treated BAC. BET surface area and pore volumes of the adsorbents decreased due to heel accumulation, and the largest reduction occurred for nitric acid-treated BAC. Pore size distributions showed that narrow micropores have a major role in the accumulation of adsorbates in heat-treated and H2-treated BAC, while larger micropores were responsible for heel formation in nitric acid-treated BAC. This is an abstract of a paper presented at the AWMA's 107th Annual Conference \& Exhibition (Long Beach, CA 6/24-27/2014).",
