Abstract |
Water scarcity is a global concern that affects a large portion of the world's population. In order to provide fresh drinkable water, adsorption based atmospheric water harvesting (AWH) has become ext...remely important in recent years. The adsorption isotherm is significant to understand the water vapor uptake behavior of the adsorbents. A proper understanding and interpretation of adsorption isotherms are critical for overall improvement of pathways of the adsorption mechanism as well as efficient design of adsorption system. In this regard, adsorption isotherm modeling was utilized for the potential adsorbents including MOF-801, AQSOA Z01-zeolites, aluminum phosphate with LTA topology (AlPO4-LTA), and alum fumarate MOF. Langmuir, Freundlich, and Dubinin Radushkevich (D-R) isotherm models have been employed for best fit of experimental plots of adsorption isotherms for studied adsorbents. The results shows that the D-R model fit the experimental plots of adsorption isotherms of studied adsorbents as compared to Langmuir, Freundlich model.show more
