Factors influencing adsorption process

Specific area of adsorbent affects adsorption of gases on solids

The surface area of an adsorbent available for adsorption is known as specific area of adsorbent. Depending on the nature of surface, impurity at the surface etc, specific area of adsorbent changes. Rough surface can adsorb more, due to greater available surface area. Similarly solids can adsorb more when powdered. When powdered, surface area increases. Hence porous and finely divide forms of adsorbent have greater adsorption power.

Activation of adsorbent

We can increase the activity of an adsorbent using different methods. Cleaning surface, making rough surface, powdering etc are some of these method.
