By activating an adsorbent, wetend to increase the adsorbing power of the adsorbent. Some ways to activate anadsorbent are:
(i) Byincreasing the surface area of the adsorbent. This can be done by breaking itinto smaller pieces or powdering it.
(ii) Somespecific treatments can also lead to the activation of the adsorbent. Forexample, wood charcoal is activated by heating it between 650 K and 1330 K invacuum or air. It expels all the gases absorbed or adsorbed and thus, creates aspace for adsorption of gases.
