A unit for the simultaneous measurement of isotherms and heats of adsorption was designed and built, and some of the results obtained are presented here. For this purpose, a Calvet heat-conducting microcalorimeter was developed and connected to a gas volumetric unit built to record adsorption isotherms. The microcalorimeter was electrically calibrated to establish its sensitivity and reproducibility, obtaining K=15.12±0.32WV−1. Additionally, the equipment was tested using the heat of neutralization for the tris-(hydroxmethyl)-aminomethane-HCL system, obtaining ΔH=−30.92±0.03kJmol−1. The unit was assembled to obtain adsorption isotherms and the corresponding heats of adsorption, from which Gibbs free energy was deduced.
