For professionals involved in water treatment, air purification, and chemical processing, understanding the specifications of activated carbon is crucial for selecting the most effective media for their applications. Among the key parameters, the iodine number stands out as a primary indicator of activated carbon's adsorptive capacity, particularly for small organic molecules and contaminants. This article delves into the significance of iodine numbers, focusing on why a 1000 iodine value is often sought after, and guides you on how to source such high-quality materials from reliable manufacturers.

What is the Iodine Number?

The iodine number quantifies the amount of iodine that activated carbon can adsorb per unit weight, typically expressed in milligrams of iodine per gram (mg/g). Iodine is a small molecule, and its adsorption onto activated carbon is primarily governed by the volume and accessibility of micropores (pores with diameters less than 2 nanometers). Therefore, a higher iodine number generally indicates a greater proportion of micropores and a higher capacity for adsorbing small organic compounds and impurities.

The Significance of a 1000 Iodine Value

An iodine number of 1000 mg/g signifies that the activated carbon possesses a highly developed microporous structure. This makes it exceptionally effective for applications requiring the removal of low molecular weight contaminants, such as:

  • Water Purification: Removing dissolved organic matter, chlorine byproducts, and taste/odor compounds.
  • Air Filtration: Capturing VOCs, formaldehyde, and other hazardous airborne pollutants.
  • Gas Phase Adsorption: Purifying gases in various industrial processes, including those requiring high purity.

When you buy activated carbon with a 1000 iodine value, you are investing in superior purification performance. It's essential to partner with a trusted activated carbon supplier or manufacturer in China to ensure you receive products that consistently meet this specification.
