With the increasingly serious environmental problems, the application of silica in environmental protection is receiving more and more attention. As a natural mineral, silica is not only abundant in resources, but also has excellent adsorption and filtration properties, making it an ideal material for treating water and air pollution.
In the field of water treatment, silica is widely used to manufacture filter media and adsorbents. It can effectively remove heavy metal ions, organic pollutants, and microorganisms from water, improving water quality. For example, in drinking water treatment, silica serves as a filtering medium that can remove suspended solids and microorganisms from water, providing safe drinking water. In industrial wastewater treatment, silica serves as an adsorbent that can remove heavy metal ions and organic pollutants from wastewater, reducing environmental pollution.

In terms of air purification, silica as an adsorbent can capture harmful gases and particles in the air, improving air quality. For example, in indoor air purification, silica serves as an adsorbent that can remove harmful gases such as formaldehyde and benzene from the air, providing a healthy indoor environment. In industrial waste gas treatment, silica serves as an adsorbent, which can remove harmful gases such as sulfur dioxide and nitrogen oxides from the waste gas, reducing air pollution.
In addition, silica is also used for soil remediation. By adding silica to contaminated soil, heavy metal ions can be fixed, reducing their harm to plants and groundwater. For example, in the remediation of heavy metal contaminated soil, silica serves as a stabilizer that can fix heavy metal ions in the soil, reducing their migration and diffusion. In the remediation of organic polluted soil, silica serves as an adsorbent that can adsorb organic pollutants in the soil, reducing their harm to plants and groundwater.
