This high iodine value indicates a strong capacity for removing small organic molecules. For applications requiring the removal of larger molecules, the Methylene Blue Adsorption Value is critical. Observed data points to values of 140 ml/0.1g for certain grades, while others specify a threshold greater than 200, suggesting a hierarchy of quality based on the intended application.

The Specific Surface Area is a fundamental indicator of the carbon's potential adsorption sites, with observed specifications stating a value of at least 1500 m²/g. This high surface area is characteristic of high-quality wood-based activated carbon. Additionally, the CTC (Carbon Tetrachloride) value is observed in the range of 40-70%, providing further insight into the pore distribution. Iron content is a contaminant that must be controlled, with observed limits set at 0.05% or 0.03% maximum. For applications in the food or pharmaceutical industries, such low iron content is often a prerequisite. The 200 Pass Rate is another quality indicator, with observed standards requiring a pass rate of 95% or higher, ensuring the powder meets the required fineness for effective dispersion in treatment processes.

Compliance, Certification, and Quality Assurance

In the global market for activated carbon, compliance and certification serve as proxies for manufacturing consistency, though specific certification statuses must be verified on a case-by-case basis. While ISO 9001 is a standard often associated with quality management systems in this sector, buyers should treat this as a general industry expectation rather than a guaranteed attribute of every listed product. The primary focus should be on verifying that the supplier can provide test reports that align with the specific technical parameters required for the application.

Quality assurance protocols should include verification of the raw material source. The product is identified as "Wooden Activated Carbon," which implies a specific feedstock that generally offers a more uniform pore structure compared to coal-based alternatives. Buyers must ensure that the supplier can trace the material origin, with Ningxia, China (Mainland) being a noted production hub. The production standards observed include mesh specifications like 180-320 mesh and classifications such as "black powder" or specific model numbers like BY-Powdered activated carbon, BY-AC, JLY-W500, and JLY-W202. These model numbers often correlate with specific performance grades, and procurement teams should request detailed datasheets that map these models to the exact chemical and physical properties required.

Cost Drivers and Pricing Structures

The pricing of wooden activated carbon powder is influenced by a complex interplay of factors, including the iodine value, particle size, and packaging requirements. The observed price range in the market spans from $0.5 to $1,825, a vast disparity that reflects differences in quality grades, order volumes, and packaging configurations. Lower prices typically correspond to standard grades with lower iodine values or bulk packaging, while premium grades with high adsorption capacities command higher unit costs.

Minimum Order Quantity (MOQ) is a significant cost driver, with observed ranges from 1 to 2,000 units. Smaller MOQs allow for flexibility in testing and initial procurement but often result in higher per-unit costs. Conversely, larger orders can leverage economies of scale to reduce the price per kilogram. Packaging also impacts the final cost; options include 25kg woven bags with PE liners, 25kg plastic woven bags, 20kg/pic, or customized bulk bags of 500kg. The choice between standard woven bags and customized packaging can alter the logistics cost and the overall price structure. Buyers should negotiate based on the total landed cost, considering that high-density products may incur higher freight charges despite lower per-unit prices.

Typical Applications and Industry Usage

Wooden activated carbon powder is a versatile material utilized across a wide array of industrial sectors. Its primary application is in water treatment chemicals, where it is employed to remove organic contaminants, chlorine, and odors. The product is also heavily used in gas phase adsorption and air purification, leveraging its high surface area to capture volatile organic compounds (VOCs). In the petrochemical, gold, food, environmental protection, electric power, and chemical industries, the carbon serves as a decolorizing agent and a catalyst support.

Specific usage scenarios include textile auxiliary agents, surfactants, rubber and plastic auxiliary agents, paper chemicals, leather auxiliary agents, electronics chemicals, coating auxiliary agents, and oil drilling auxiliary agents. The versatility of the product is further evidenced by its application in industrial decolorization and gas purification. For instance, in the food industry, the low iron content and high purity are essential to prevent contamination. In the gold industry, the carbon is used for the adsorption of gold from cyanide solutions. The ability to customize the product, as noted in the market data, allows suppliers to tailor the carbon's properties to meet the specific demands of these diverse sectors.

Supplier Evaluation and Procurement Strategy

Selecting a reliable supplier requires a rigorous evaluation process that goes beyond simple price comparison. Buyers should prioritize suppliers who demonstrate transparency in their product specifications and can provide consistent test results.
