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.
