Choosing the right activated carbon is critical for achieving optimal performance in any purification application. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of understanding key product properties to make an informed selection.

The effectiveness of activated carbon is largely determined by its physical and chemical characteristics. Among the most important are:

  • Specific Surface Area: This is arguably the most crucial property. A larger surface area, typically measured in m²/g, indicates a greater capacity for adsorption. Activated carbons derived from coal, like those offered by NINGBO INNO PHARMCHEM CO.,LTD., are known for their extensive surface areas, often exceeding 950 m²/g.
  • Iodine Adsorption Value: Often reported in mg/g, this metric specifically measures the micropore content of the activated carbon. A higher iodine number signifies better adsorption of smaller molecules and indicates a higher degree of activation. Values ranging from 600-1100 mg/g are common for high-performance carbons.
  • Particle Size and Distribution: The size of the activated carbon granules or particles affects both the adsorption rate and the pressure drop across a filter bed. For vapor phase applications, smaller particles offer faster kinetics but higher pressure drop, while for liquid phase applications, a balance is sought. Common specifications include mesh sizes like 4-8 mesh or 6-12 mesh.
  • Mechanical Strength: The durability of the activated carbon is important, especially in applications where it undergoes physical stress or regeneration cycles. High mechanical strength ensures the carbon retains its structure and adsorptive capacity over time.
  • Ash Content and Purity: For specific applications, such as food-grade uses, low ash content and high purity are essential. The source material and manufacturing process significantly influence these factors.
