What do you understand by activation of adsorbent? How is it achieved?
Explanation The activation of adsorbent can be achieved in the following ways: 1. The first way of activating the adsorbent is to increase the surface area of an adsorbent by breaking it into smaller pieces. 2. The activation can also be done by some specific treatments. For example, the activation of wood charcoal is done by heating it at a temperature between 650 K and 1330 K in vacuum or air. In this process, all the gases absorbed or adsorbed are expelled which creates a space for adsorption of gases. Final Answer Increasing the capacity of adsorption for an adsorbent is known as activation of adsorbent. It can be activated by increasing the surface area of the adsorbent and also by specific treatment.
