Adsorption Isobars
These are plots of x / m us temperature t at constant pressure. For physical and chemical adsorption, they are shown below.
Adsorption Isostere
These are the plot of temperature versus pressure for a given amount of adsorption
Applications of Adsorption
1. For production of high vacuum.
2. Gas masks containing activated charcoal is used for breathing in coalmines. They adsorb poisonous gases.
3. Silica and aluminium gels are used as adsorbents for controlling humidity.
4. Removal of colouring matter from solutions. 5. It is used in heterogeneous catalysis.
6. In separation of inert gas. 7. As adsorption indicators.
