Experimental study of isotherms and kinetics for adsorption of water on Aluminium Fumarate

This article presents the adsorption characteristics of Aluminium Fumarate (Al-Fum) Metal Organic Framework (MOF) and water systems for the temperatures ranging from 25 °C to 60 °C and pressures up to saturation conditions. The amount of water uptakes is measured by a gravimetric analyser under stat...
