adsorption is processs of accumulation of liquid/gases on solid surface. reversible adsorption is seen in physical adsorption where increase in pressure increases the adsorption and decrease in pressure decrease adsorption of molecules to surface that is desorption takes place ...

They are as follows: 1)Temperature 2)Pressure 3) Surface of adsorbent 4) Nature of adsorption process (either chemi-adsorption of phsi-adsorption) that all these are the major factors affecting the rate of adsorption. ...

Much would depend on the precise circumstances. In industrial cases, and some clinical situations, this can be done using pressure swing adsorption. Please see the link. ...

At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high...

An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is cryogenic distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon. Other methods such as Membrane, pressure swing adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA), are commercially used to separate a single component from ordinary air. ...

Frenlich adsorption isotherm has no theoretical basis. There are high chances of it failing when the concentration of the adsorbate is high. The equation is, usually, invalid at high pressure. ...

Yes. Pressue effects both adsorption and absorption of oxygen. I assume you really did mean adsorption (and not absorption) but just in case, this answer addresses both - since the answer is similar. As pressure increases, the fugacity of oxygen in the liquid or vapor phase will also increase. In order to stay in equilibrium, you would expect the concentration of oxygen on a surface (adsorption) to increase as well. There is one caveat in that if the oxygen is in a mixture,...

ADSORPTION ISOTHERM A mathematical equation, which describes the relationship between pressure (p) of the gaseous adsorbate and the extent of adsorption at any fixed temperature, is called adsorption isotherm. The extent of adsorption is expressed as mass of the adsorbate adsorbed on one unit mass of the adsorbent. Thus, if x g of an adsorbate is adsorbed on m g of the adsorbent, then Extent of adsorption = z/m Various adsorption isotherms are commonly employed in describing the adsorption data. (1) Freundlich adsorption isotherm (i) Freundlich adsorption isotherm is obeyed by...

yes it does...even though physical adsorption is an exothermic reaction, its enthalpy of adsorption is pretty low aroun 20 to 40 kJ/mol ...

Re-adsorption is defined as the absorption of a substance that was previously removed. This process commonly occurs with water in the body. ...

Adsorption is generally a physical change.

adsorption means that the molecules of one phase are present in higher concentration at the surface of the second phase. ex.inert gases on charcoal when the temperature is increasing the adsorption decreases.so , we can say the adsorption is always exothermic. ...

The Langmuir equation (also known as the Langmuir isotherm, Langmuir adsorption equation or Hill-Langmuir equation) relates the coverage or adsorption of molecules on a solid surface to gas pressure or concentration of a medium above the solid surface at a fixed temperature. ...

Adsorption is an absorption at the surface of materials.

Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. ...

adsorption is when there are spaces in molecular structure of material. the adsorbed substance is held in these spaces like in sponge. ...
