The temperature dependence of isosteric heat of adsorption on the heterogeneous surface
Journal of Catalysis, 1972Abstract The determination of the isosteric heat of adsorption, qst, from a series of adsorption isotherms can provide information on the energetics of the gas-solid interface as well as the distribution of energetic sites on the solid surface. In practice, qst is often assumed to be independent of temperature within a short temperature range.

We used a dynamic method to measure the adsorption isotherms for the gases ethane, propane, and n -butane on polystyrene at 273, 298, and 303 K. Concentrations were in the range from 500 to 10,000 ppm in a helium carrier. The isotherms can be represented by either Freundlich or Chakravarti-Dhar types.

Isosteric heats of adsorption of selected compounds on diesel particulate matter
Environmental Science & Technology, 1982Isosteric heats of adsorption were determined for 18 compounds with low injection volumes. The isosteric heats of adsorption of benzene and hexane on the pretreated Diesel samples were compared with those of the same compounds on a graphitized carbon black.

Improvement of Accuracy for Determination of Isosteric Heat of Hydrogen Adsorption
Korean Journal of Materials Research, 2017Isosteric heat of hydrogen adsorption is one of the most important parameters required to describe solid-state hydrogen storage systems. Typically, it is calculated from adsorption isotherms measured at 77K (liquid N2) and 87K (liquid Ar). This simple calculation, however, results in a high degree of uncertainty due to the small temperature range ...
