Harnessing the intrinsic thermodynamic properties of adsorption and absorption processes may result in the generation of effective thermal energy storage such as sorption heat pumps. Two specific ...

A hybrid adsorbent (CES), coffee grounds, eggshell powder and sericite as a binder, was prepared to remove Pb(II) from aqueous solution. The Fourier-transform infrared spectroscopy analysis showed ...

Commercial heat packs (containing iron and water, or supersaturated sodium acetate) and cold packs (various ammonium salts) can be used to show exo- and endothermicity. Heat packs that contain iron ...

A finely divided substance has a large surface area. We know that adsorption is asurface phenomenon & is directly proportional to the surface area. Whether adsorption is physisorption or chemisorption ...
