The correct answer is: Activated Charcoal.
Activated charcoal is a highly porous form of carbon that has been processed to increase its surface area. This makes it an excellent adsorbent, meaning that it can attract and hold onto other molecules. Activated charcoal is used in a variety of applications, including water purification, air filtration, and medicine.
Charcoal is a form of carbon that is produced by the incomplete combustion of organic materials, such as wood, coal, or bone. It is a black, porous solid that has a high surface area. Charcoal is used in a variety of applications, including water filtration, air purification, and cooking.
Activated coconut charcoal is a type of activated charcoal that is made from coconut shells. It is a highly porous form of carbon that has been processed to increase its surface area. Activated coconut charcoal is used in a variety of applications, including water purification, air filtration, and medicine.
Carbon black is a form of carbon that is produced by the incomplete combustion of hydrocarbons. It is a black, powdery solid that has a high surface area. Carbon black is used in a variety of applications, including rubber production, plastics production, and printing inks.
Of the four options, activated charcoal has the highest surface area and is therefore the best adsorbent.
