Due to its high specific surface area and rich pore structure, precipitated silica exhibits excellent surface adsorption performance, which makes it have a wide application prospect in environmental governance. The following are some directions of the surface adsorption properties of precipitated silica and its application in environmental governance:

Adsorption performance research: study the adsorption performance of precipitated silica on pollutants under different environmental conditions, including the adsorption ability of organic matter, heavy metal ions, dyes, gas pollutants, etc. By controlling the pore structure and surface properties of silica, its adsorption performance is optimized.

Water treatment: Precipitated silica can be used as an adsorbent for water treatment to remove organic matter, heavy metal ions, drug residues and other pollutants in water. Its high specific surface area and microporous structure can provide a large number of active adsorption sites to achieve efficient adsorption and removal of pollutants in water.

Air purification: Precipitated silica can be used for air purification, absorbing and removing harmful gases, volatile organic compounds (VOCs) and other pollutants in the air. Its high adsorption performance can effectively improve indoor air quality and reduce the release of harmful gases.

Noise Absorption: The porous structure and high surface area of precipitated silica make it potentially useful in noise absorption. As a noise absorbing material, it slows down the propagation of sound waves and reduces noise pollution.

Treatment of soil and wastewater: Precipitated silica also has application prospects in the treatment of polluted soil and wastewater. By adding silica to soil or wastewater, harmful substances can be adsorbed and removed, and soil and wastewater can be purified.

Environmental remediation: Precipitated silica can be used in environmental remediation projects, such as adsorption and removal of toxic substances in industrial wastewater, removal of pollutants in water and soil, etc.

It should be pointed out that the application of precipitated silica in environmental governance is affected by many factors, including the nature of silica, the type and concentration of pollutants, and environmental conditions. Therefore, in practical applications, it is necessary to make reasonable selection and design according to specific conditions. At the same time, it is also necessary to consider the recycling and environmental impact of silica to promote its sustainable application in environmental governance.
