WebJul 11, 2024 · Adsorption is a process in which a component or components from a gas phase or a liquid phase are attached to the surface of a solid phase when the gas phase or the liquid phase is brought in … WebNov 22, 2013 · 11. Activated charcoal is a great adsorbent because of it's huge surface area. While it doesn't bind very many ions/atoms/molecules per surface area (which is the characteristic of a 'good' adsorbent), due to very big surface area per unit of mass it can adsorb a lot of particles. Actually, process of 'activating' charcoal is designed to ...

Adsorption is defined as the phenomenon in which there is the accumulation of one substance on the surface of the other substance. It can also be defined as the change in concentration at the interfacial layer between two phases of the system due to surface forces.
