Question

Consider the following statements:Activated carbon is a good and an attractive tool to remove pollutants from effluent streams and to remediate contaminants from various industries.Activated carbon exhibits a large surface area and a strong potential for adsorbing heavy metals.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?

Accepted Answer

Activated carbon is a popular and effective method for removing pollutants from water, particularly in wastewater treatment and industrial processes. Activated carbon is produced from environmental wastes with high carbon content. Lignocellulosic and coal materials have been used as raw materials planned for manufacturing of activated carbons. There are two approaches for preparing activated carbon that can be used in water purification processes: physical activation and chemical activation. Activated carbon has good potential for adsorbing heavy metals because of its greater surface area, microporous ability, and chemical complexity of its external area. Activated carbon can be made relatively easily at home using materials like coconut shells or wood and is therefore an attractive tool to remove pollutants. Hence, Both statement II and Statement III are correct and both of them explain Statement I.
