    Trace contaminant studies of HSC adsorbent
    (1979) Yieh, Dennis Tzyy-nian; Davis, S. H.; Deans, H. A.; Leland, Thomas W.
    The adsorption and desorption of fifteen trace contaminants on HSC (polyethylenimine coated acrylic ester) adsorbent have been experimentally investigated with the following two objectives: 1) To test the removal potential and the adsorption reversibility of the selected trace contaminants, 2) to test the effect a preadsorbed trace contaminant has on the CC^ adsorption capacity. The experimental method for acquiring the adsorption equilibrium data used in this study is based on the volumetric (or displacement) concept of facuum adsorption. From the experimental results, it has been found that the HSC adsorbent has good adsorption potential for contaminants of alcohol compounds, ester,s and benzene compounds; whereas, adsorption of ketone compounds, oxidizing and reducing agents are detrimental to the adsorbent. In addition, all 'liquid' contaminants reduce the CO2 capacity of HSC adsorbent.
