Wood-based powdered activated carbon is renowned for its unique set of physical and chemical properties that make it an exceptional adsorbent across a wide spectrum of industrial applications. NINGBO INNO PHARMCHEM CO.,LTD. delves into these characteristics to illuminate why this material is a preferred choice for purification and decolorization tasks.

One of the most defining features of wood-based activated carbon is its pore structure. It typically exhibits a well-developed macroporosity and mesoporosity. Macropores are larger voids that facilitate the rapid diffusion of larger molecules to the internal surfaces, while mesopores offer significant surface area for adsorption. This combination is particularly advantageous for decolorization processes, where larger color molecules need to be efficiently adsorbed. The high surface area, often exceeding 1000 m²/g, is a direct consequence of this pore development.

The purity of wood-based activated carbon is another significant property. When produced through steam or phosphoric acid activation, it generally contains lower levels of ash and inorganic impurities compared to some coal-based carbons. This high purity is crucial for applications where the activated carbon might come into contact with sensitive products, such as in the pharmaceutical industry or for food grade applications. Meeting standards like Food Chemical Codex (FCC) or NSF certification further underscores this purity.

Its adsorption capacity, measured by parameters like Iodine Value and Methylene Blue Value, indicates its efficiency in removing specific types of contaminants. A high Iodine Value signifies excellent adsorption of smaller molecules, while a high Methylene Blue Value points to strong adsorption of larger molecules and color bodies. Wood-based activated carbon typically performs very well in Methylene Blue adsorption, aligning with its effectiveness in decolorization.

The physical form of powdered activated carbon (PAC) means it has a very small particle size, leading to a high external surface area and very fast adsorption kinetics. This makes it ideal for batch treatment processes where rapid contact time is needed. However, the fine nature of PAC also requires efficient downstream filtration to separate it from the treated liquid. Understanding the wood activated carbon price often involves considering the grade, mesh size, and purity level.
