Description

• Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are known as the most detected per- and polyfluoroalkyl substances (PFAS) in various environmental compartments. Our Mesoporous adsorbents for perfluorinated compounds can remove approximately 99% of PFOA and PFOS from water or air.

Product Features

1. Large specific surface area and rich pore structure: Mesoporous adsorbents for perfluorinated compounds have a huge surface area, a rich pore structure, and high accessibility of adsorption sites, which increases the capacity and efficiency for adsorbing PFAS.

2. Strong selective adsorption: High adsorption capacity, proven selective for PFOA and PFOS, with minimal impact on the adsorption of other coexisting substances.

3. Excellent adsorption performance: High contents of primary adsorption sites in the adsorbents provide the high adsorption capacity for perfluorinated compounds, thereby reducing the concentration of PFOA and PFOS in water or gas to meet relevant environmental standards and safety requirements.

4. Excellent chemical stability and regeneration performance: Mesoporous adsorbents for perfluorinated compounds are a very corrosion-resistant material, which can maintain stable adsorption performance over a wide pH range. After simple regeneration treatment, their adsorption performance can be effectively restored, reused, and cost-saving.

Scope of Application

• This product is suitable for the purification treatment of various water bodies and gases containing PFOA and PFOS, such as industrial wastewater treatment, drinking water purification, air purification, and other fields.
• Specially suitable for occasions with high requirements for PFOA and PFOS removal, such as wastewater treatment in industries such as electronics, chemical, and pharmaceutical, as well as the production and supply of high-end drinking water.

How to Use

1. Water Treatment：For an adsorption system using mesoporous adsorbents for perfluorinated compounds, the process of adding an appropriate dose, mixing, and allowing sufficient contact is a standard method for removing PFOA and PFOS from water. The specific dosage and contact time depend on several factors. After the reaction is completed, the perfluorinated compound (PFAS) adsorbent needs to be separated from the water by filtration, precipitation, and other separation methods.

2. Gas Treatment：Fill the mesoporous adsorbents for perfluorinated compounds into gas purification equipment, such as adsorption towers or filters. When gases containing PFOA and PFOS pass through a chamber or vessel containing a mesoporous adsorbent for perfluorinated compounds. The PFOA and PFOS molecules in the gas come into full and prolonged contact with the adsorbent's surface. By capturing the PFOA and PFOS molecules, the adsorbent purifies the gas before it is discharged. For effective purification, the replacement or regeneration schedule for mesoporous adsorbents for perfluorinated compounds must be determined by monitoring the system and analyzing the gas flow rate, pollutant concentration, and adsorbent capacity.

Precaution

1. Store in a cool and well-ventilated warehouse to prevent moisture and contamination.

2. Optimizing the use of mesoporous adsorbents for perfluorinated compounds requires controlling the dose of adsorbent and reaction conditions based on the characteristics of the specific contaminants and the treatment environment.

3. Strict quality testing of mesoporous adsorbents for perfluorinated compounds is essential to verify both performance and safety before reuse.

4. Local and regional authorities determine specific emission standards and permits. So the relevant environmental regulations and standards should be followed when treating wastewater or exhaust gas to remove longer-chain PFAS like PFOA and PFOS.
