Meaning of adsorption in chemistry
WebJun 27, 2024 · As far as I know, the definition of the Danckwerts boundary condition says that after the gas is introduced into the column, the convection transport mechanism is associated with the diffusion, which causes a concentration step change at the inlet. WebApplication of adsorption. Conclusion. In 1881, a German physicist named Heinrich Kayser created the term adsorption. The processes happening at interfaces or surfaces concern surface chemistry. Solid or gas help describing the interface among a solid and a gas. There is no contact between the gases because they are fully miscible.
