Text SolutionText solutionverified iconVerified

Activation of adsorbent is the increasing of the adsorbing power of the adsorbent. It means increasing the rate of adsorbption. it can be achieved by the following methods.
(1) To activate metallic adsorbents, their surface is made rough by mechanical rubbing or by depositing finely dispersed metals on the surface of adsorbent by electroplating or by some chemical reactions.
(2) Increase the surface area by sub-dividing into smaller pieces.
(3) Strongly heat in contact with super heated steam or in vacuum at a temperature of 623-1273 K. This removes already adsorbed gases.
