During the adsorption of krypton

WebMay 30, 2024 · Heinrich Kayser, the German physicist was the first to coin the term adsorption. Adsorption can be explained as a surface phenomenon where particles remain attached on the top of a material. Generally, it comprises the molecules, atoms, liquid, solid in a dissolved stage, even the ions of a gas that are attached to the surface. WebIn a two-column system, the removal efficiency and adsorption capacity for Kr on these two MOFs were further increased upon removal of Xe on the first bed. These results show that there is a promising future for the use of MOFs for the removal of noble gas radionuclides from process off-gases during reactor operation or reprocessing of ...
