Abstract
With the increase in global temperatures and the shortage of freshwater resources, atmospheric water vapor has become a promising alternative source of water. In recent decades, various adsorbents have been developed to capture this moisture and convert it into fresh water. Aluminum-based Metal-Organic Frameworks (MOFs) have gained significant attention due to their unique properties as adsorbent materials. These frameworks are composed of metal ions connected by organic linkers, forming highly porous networks with large surface areas. In this study, aluminum fumarate MOF was synthesized using the solvothermal method, with fumaric acid as the linker and dimethylformamide (DMF) as the organic solvent. Formic acid was used as a modulator to reduce the reaction time. The synthesized MOF was characterized using FTIR, XRD, SEM-EDX, and BET analyses. Moisture adsorption tests were conducted at 25°C and 30°C, using local humidity conditions in Rasht (high relative humidity) and Ardestan (low relative humidity). Four isotherm models, including Langmuir, Freundlich, Dubinin–Radushkevich, and Frenkel–Halsey–Hill, were evaluated to describe water adsorption behavior. The dynamic water adsorption process on aluminum fumarate was well described by the linear driving force model and could be divided into monolayer, multilayer, and cluster adsorption phases.
