Acid-Washed Activated Carbon: High-Purity Adsorption for High-Precision Purification Needs

I. Process Characteristics and Core Advantages

As industries such as water treatment and food processing demand increasingly higher levels of purification precision and material purity, acid-washed activated carbon has emerged as a preferred adsorbent for demanding purification applications, thanks to the high purity achieved through specialized refining processes. Produced using a professional acid-washing and refining method—involving steps such as acid solution immersion, steam heating, and multi-stage rinsing—this product effectively removes soluble impurities and heavy metals from the carbon's pores. It precisely adjusts the pH range while optimizing the internal pore structure, thereby enhancing adsorption performance and extending service life.

II. Grading Specifications and Physicochemical Indicators

This acid-washed activated carbon is available in two grades, A and B, covering various particle sizes such as 10-24 mesh, 30-60 mesh, and 60-200 mesh. The pass rate for all grades is no less than 95%, making it suitable for filling various purification equipment. In terms of performance, Grade A features an iodine value of ≥1000 mg/g and a methylene blue decolorization capacity of ≥9 mL/0.1g, while Grade B offers an iodine value of ≥900 mg/g and a methylene blue decolorization capacity of ≥7 mL/0.1g, ensuring robust adsorption capacity. Both grades exhibit an ash content of ≤3%, a stable pH range of 5–7, and a moisture content of ≤10%; they possess mild chemical properties and pose no risk of secondary pollution.

III. Applicable Fields and Application Value

Currently, this product is widely used in water treatment and purification, food processing and purification, and other fields, effectively removing off-colors, odors, organic impurities, and trace heavy metals from the system. Characterized by high purity, low ash content, and stable adsorption performance, this acid-washed activated carbon provides reliable material support for high-precision purification scenarios, helping enterprises consistently improve the quality of their purification processes.
