Consider the following statements:
Statement I:
Activated carbon is a good and an attractive tool to remove pollutants from effluent streams and to remediate contaminants from various industries.
Statement II:
Activated carbon exhibits a large surface area and a strong potential for adsorbing heavy metals.
Statement III:
Activated carbon can be easily synthesized from environmental wastes with high carbon content.
Which one of the following is correct in respect of the above statements?
Activated carbon is widely used to clean pollutants because of its unique properties and sustainable production methods. ✅ Statement I: Correct. Activated carbon effectively removes pollutants from industrial effluents due to its high adsorption capacity. It’s commonly used in water treatment and pollution control. ✅Statement II: Correct. This is because activated carbon has an extremely large surface area, created by its porous structure, allowing it to trap heavy metals and other contaminants efficiently. ✅ Statement III: Correct. Moreover, activated carbon can be produced easily and cost-effectively from carbon-rich wastes like coconut shells, rice husks, and other agricultural residues, making it an eco-friendly option. Thus, both Statement II and Statement III are correct, and together they explain why Statement I is true.
