To activate the adsorbent, we have to increase the adsorbing power of adsorbent.
It can be done by several ways.
If the surface area of adsorbent is increased, it can increase the adsorbing power.
The surface area can be enhanced simply by breaking the adsorbent into various smaller pieces or turning it into powder.

By increasing the surface area of the adsorbent. This can be done by breaking it into smaller pieces or powdering it. (ii) Some specific treatments can also lead to the activation of the adsorbent. For example, wood charcoal is activated by heating it between 650 K and 1330 K in vacuum or air.
