Exploration of the application of white carbon black in the field of environmental protection White carbon black has shown great potential for application in the field of environmental protection. As an environmentally friendly inorganic non-metallic material, white carbon black has high chemical stability and good adsorption performance, and can be used in various fields such as sewage treatment and air purification. In wastewater treatment, white carbon black can be used as an adsorbent to remove heavy metal ions and organic pollutants from water; In air purification, white carbon black can be used to prepare efficient filtration materials that remove small particles and harmful gases from the air. In addition, white carbon black can also be used in biological filtration processes by adding hydrophobic silica to enhance the migration of hydrophobic organic compounds and improve the removal efficiency of biofilms. With the improvement of environmental awareness and the strengthening of environmental policies, the application of white carbon black in the field of environmental protection will continue to expand and deepen, contributing to the improvement of environmental quality.
