Which of the following acts as best adsorbent? (1) Charcoal (2) Activated Charcoal (3) Activated Coconut Charcoal (4) Carbon black
by

1 Answer

Answer :

(3) Activated Coconut Charcoal Explanation: Activated coconut charcoal is a highly absorbent material with millions of tiny pores that can capture, bind, and remove unwanted materials. The porous surface has a negative electric charge that attracts positively charged toxins and gas to be carried easily out of the body. It is used medicinally as well as in air and water purifiers.
