Is it true that charcoal serves as an excellent adsorbent due to its high surface area and porosity?

Yes. Activated charcoal is widely documented across scientific literature as an excellent adsorbent, with multiple studies confirming that its high surface area and porosity directly drive its superior adsorption capacity for gases and aqueous pollutants.

The analysis

The claim states that charcoal serves as an excellent adsorbent due to its high surface area and porosity. Multiple retrieved papers (such as [0], [2], [3], [4], [6], [7], [8], [9]) explicitly connect the high specific surface area and developed porosity of activated carbons/charcoal to their high adsorption capacities for various gases and pollutants. There are no papers refuting this well-established physicochemical principle.
