NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing purification technologies, and understanding the science behind our products is key. Coconut shell activated carbon is renowned for its efficacy in removing volatile organic compounds (VOCs), a critical concern in both water and air purification. The secret lies in its unique physical structure and chemical properties, which we meticulously engineer into our products.

The fundamental mechanism is adsorption, a surface phenomenon where molecules of a substance (adsorbate) adhere to the surface of another substance (adsorbent). For activated carbon, this adsorption is facilitated by an exceptionally large internal surface area, developed through a process of controlled activation. Coconut shells, when carbonized and activated, form a material with a high density of micropores, typically with pore sizes ranging from 0.5 to 10 nanometers. These pores are perfectly sized to trap VOC molecules, which are typically small organic compounds that readily vaporize.

VOCs, such as benzene, toluene, and trichloroethylene (TCE), can originate from industrial processes, household products, and even natural sources, contaminating water and air. Coconut shell activated carbon's microporous structure offers a higher affinity for these specific molecules compared to larger pores that might be found in other carbon types. This selectivity is crucial for effective purification. NINGBO INNO PHARMCHEM CO.,LTD. ensures our activated carbon has an optimized pore size distribution to maximize VOC capture efficiency.

The effectiveness of coconut shell activated carbon in VOC removal is further enhanced by its surface chemistry. While the primary mechanism is physical adsorption driven by van der Waals forces, the presence of functional groups on the carbon surface can also play a role in chemisorption for certain VOCs. Our manufacturing process aims to maintain a clean and optimized surface to ensure the highest adsorption capacity.

In practice, whether used in water filters or air purifiers, the VOCs in the fluid stream diffuse into the pores of the activated carbon and are held there. The high hardness of coconut shell activated carbon also means it can withstand the rigors of filtration systems, maintaining its structural integrity and adsorptive capacity over time. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed technical specifications, including iodine numbers and CTC activity, to assure customers of our product's performance in VOC removal, ensuring cleaner water and air for various applications.
