four properties of a good adsorbent
Answers
They must have high abrasion resistance, high thermal stability and small pore diameters, which results in higher exposedsurface area and hence high capacity for adsorption. The adsorbents must also have a distinct pore structure that enables fast transport of the gaseous vapors.

Explanation:
£ They must have high abrasion resistance, high thermal stability and small pore diameters, which results in higher exposed surface area and hence high capacity for adsorption. The adsorbents must also have a distinct pore structure that enables fast transport of the gaseous vapors.
£ In general, the more important characteristics of a good adsorbent are: large surface area, available polar sites, and reproducibility in the degree of activation.
£ Adsorption refers to the existence of a higher concentration of any particular component at the surface of a liquid or a solid phase.
£ Adsorption is accompanied by decrease in the (free energy change) of the system when , adsorption equilibrium is said to be established.
