| Swine farming emit several odorous volatile organic compounds, one of which is p-cresol. Considering the layout of a swine barn, adsorption is one of the most suitable technologies for mitigating organic pollutants. In this study, commercial granular activated carbon (GAC) was tested as an adsorbent for removing p-cresol from aqueous solution. The objectives were to: 1) determine the combined effect of temperature, pH, and adsorbent dose on adsorption, (2) investigate the effect of volatile fatty acids and aldehydes on adsorption of p-cresol, (3) determine adsorption kinetics and isotherms, (4) study the effect of solvent on adsorption, (5) propose a possible mechanism of adsorption, and (6) discuss practical implications and design calculations for... |
