Difference between Adsorbent and absorbent molecule
Difference between Adsorbent molecule and absorbent molecule
are in tabular form below –
Adsorbent molecule |
Absorbent molecule |
1) Adsorbent bind onto the surface of the absorbent most commonly through Vander- Waal interactions or through covalent bonds. | Absorbent material remains within spaces of the absorbent without having a chemical relationship being perfectly intact as with it free. |
2) The concentration of the adsorbed molecule is always greater at the free phase. | The concentration of the absorbed molecule is low at the free phase. |
3) The substance on which the surface process takes place is called adsorbent. | Absorbent is a bulk phenomenon, occurs throughout the substance. |
4) It increases steadily. | It occurs at uniform rate. |
5) It is affected by temperature. | It is not affected by temperature. |
6) The adsorbate remains on the surface does not enter into the bulk or interior of the solid or liquid. | The absorbate is uniformly distributing throught the body of solid or liquid. |
7) The concentration at the bottom adsorbent is different from that in bulk. | The concentration is constant throughout the medium. |
8) It is rapid in the beginnings and slows down near the equilibrium. | It occurs at uniform rate. |
9) Example of the adsorbent are: Some examples of good adsorbents includes alumina gel zeolites, activated carbon, graphite. | Examples of absorbent are: Anhydrous calcium chloride. |
