Measurement and Thermodynamic Evaluation of VOC and Water Adsorption Equilibria onto Granulated Activated CarbonA laboratory test apparatus was used to obtain adsorption onto granular activated carbon at temperatures between 50°C and 130°C. Despite the kinetic advantage of activated carbon cloth, which was solely investigated in the apparatus before, it is shown that by a new sample holder it is also possible to obtain adsorption isotherms onto granulated activated carbon fast, economically and within a large measuring range. Measurement results, namely adsorption isotherms, were evaluated by the ALI c model as well as by the models of Dubinin-Asthakov, Toth and Do&Do. The model equations were evaluated regarding their fitting quality and further criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
