Microplastics are tiny plastic particles less than five millimeters in size that contaminate water sources worldwide. Their presence poses serious threats to aquatic life and human health. As the search for effective filtration methods continues, activated carbon has emerged as a promising solution.
What Is Activated Carbon?
Activated carbon, also known as activated charcoal, is a form of carbon processed to have a high surface area. This porous material can adsorb a wide range of contaminants, including chemicals, toxins, and pollutants. Its extensive surface area makes it highly effective in water purification processes.
The Role of Activated Carbon in Removing Microplastics
Recent studies suggest that activated carbon can adsorb microplastics from water due to its porous structure. Although microplastics are physical particles, their surface can attract and hold onto smaller particles and chemicals through physical and chemical interactions.
Mechanisms of Adsorption
Activated carbon removes microplastics mainly through:
- Physical adsorption: Microplastics adhere to the surface of activated carbon due to Van der Waals forces.
