Question

What do you mean by activation of adsorbent?

Answer 1

Activation of adsorbent means increasing the absorbing power of an adsorbent

This can be done by increasing the surface area of the adsorbent which can be achieved by any of the following ways :-

●By making the surface of adsorbent rough.

● By breaking it in small pieces.

hope it helps you :-)

Answer 2

Answer:

By activating an adsorbent, we tend to increase the adsorbing power of the adsorbent.  Some ways to activate an adsorbent are:  

(i) 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. It expels all the gases absorbed or adsorbed and thus, creates a space for adsorption of gases.
