Investigation of coconut husk as a low-cost adsorbent for removing methylene blue, methylene orange and tetracycline
Accepted Answer
Coconut husk is a promising low-cost adsorbent for removing pollutants like methylene blue, methylene orange, and tetracycline from wastewater. This is due to its abundance of functional groups like hydroxyl, carboxyl, and amino groups, which can interact with the dye molecules through adsorption mechanisms like electrostatic attraction, hydrogen bonding, and π-π interactions. The effectiveness of coconut husk as an adsorbent depends on factors such as its particle size, surface area, and pH of the solution. The study of adsorption isotherms and kinetics helps to understand the adsorption process and optimize the removal efficiency.
