How does coconut shell-derived activated carbon (CSDAC) function as an adsorbent for nitrobenzene and dinitrobenzene?

Label:chem

Topic
Activated carbon is a commonly used adsorbent material for removing organic pollutants from water. CSDAC is a sustainable and cost-effective alternative to conventional activated carbon, derived from abundant and renewable coconut shells.
Answer
CSDAC functions as an effective adsorbent for nitrobenzene and dinitrobenzene through its high surface area, developed porosity, and surface functional groups. These properties facilitate efficient adsorption via hydrogen bonding, Van der Waals forces, and π–π interactions. The adsorption process is rapid, reaching equilibrium within 10 minutes, and is spontaneous and endothermic, with higher temperatures favoring adsorption.
