At NINGBO INNO PHARMCHEM CO.,LTD., we believe that a deep understanding of our products' technical specifications is key to their optimal application. Coal-based activated carbon, while broadly recognized for its adsorptive capabilities, owes its specific performance characteristics to its intricate pore structure and surface properties. Understanding these elements, such as specific surface area, pore volume, and the significance of parameters like the iodine number, is crucial for achieving targeted purification, such as the removal of pesticides from water.

The effectiveness of activated carbon is largely determined by its pore network. Micropores (less than 2 nm) are ideal for adsorbing smaller molecules, while mesopores (2-50 nm) and macropores (greater than 50 nm) are better suited for larger contaminants. Coal-based activated carbons often exhibit a balance of micropores and mesopores, making them versatile for various applications. For instance, in pesticide removal from water, the size of the pesticide molecules dictates which pore sizes will be most effective. A carbon with a suitable mesopore structure, in addition to micropores, can enhance adsorption by providing larger pathways for contaminant molecules to reach active sites.

The iodine number is a standard metric used to quantify the micropore content and, by extension, the activity level of activated carbon, with higher numbers indicating greater activation. Similarly, other parameters like molasses number can indicate mesopore capacity. When considering the purchase of activated carbon, especially for specialized applications like pesticide adsorption, NINGBO INNO PHARMCHEM CO.,LTD. can guide clients in selecting materials with pore structures and adsorptive properties that precisely match their needs. This technical insight ensures that clients can buy coal activated carbon that delivers superior performance and achieves desired purity levels.
