Overview
Attapulgite powder adsorbent is a naturally occurring hydrated magnesium aluminum silicate clay mineral. It is valued for its unique fibrous structure, which provides a high surface area and excellent adsorption properties. The material is commonly sourced from deposits in China, the United States, and other regions with significant attapulgite reserves. Due to its versatile adsorption capabilities, attapulgite powder is widely used in industrial, environmental, and agricultural applications. It is particularly effective in removing heavy metals, organic pollutants, and moisture from gases and liquids. The material is also known for its thermal stability and inertness, making it suitable for high-temperature processes.
Physical and Chemical Properties
Attapulgite powder adsorbent exhibits a fibrous morphology with a high surface area, typically ranging from 100 to 300 m²/g. This property enhances its adsorption capacity for various contaminants. The material is chemically inert and stable under a wide range of pH conditions, making it suitable for diverse applications. Its thermal stability allows it to withstand temperatures up to 1000°C without significant degradation. The powder is insoluble in water and organic solvents, which ensures its durability in aqueous and non-aqueous environments. These properties make attapulgite powder a reliable choice for long-term use in demanding industrial settings.
Main Applications
Attapulgite powder adsorbent is extensively used in wastewater treatment to remove heavy metals, dyes, and other pollutants. Its high adsorption capacity and cost-effectiveness make it a preferred choice for industrial effluent treatment plants. In the gas purification sector, the material is used to adsorb volatile organic compounds (VOCs) and sulfur compounds. It also serves as a catalyst carrier in chemical reactions due to its stable structure. Additionally, attapulgite powder is used as an animal feed additive to improve gut health and as a desiccant in packaging to control moisture.
Safety and Storage
While attapulgite powder is generally non-toxic, prolonged exposure to airborne particles may cause respiratory irritation. It is recommended to use dust masks and proper ventilation when handling the powder in bulk. Skin contact is not harmful, but gloves should be worn to prevent dryness. Storage conditions are critical to maintaining the material's effectiveness. The powder should be kept in a cool, dry place, sealed in moisture-proof containers. Avoid exposure to direct sunlight or high humidity, as these can reduce its adsorption capacity over time.
B2B Procurement Guide
When procuring attapulgite powder adsorbent, buyers should prioritize suppliers with verified quality certifications. Key specifications to check include purity (typically 90-98%), particle size (usually 200-400 mesh), and moisture content (below 10%). Bulk purchases often come with cost advantages, but it's essential to assess storage capabilities to prevent degradation. Sampling and lab testing are recommended to ensure the material meets application requirements. Reliable suppliers should provide detailed technical data sheets and material safety data sheets (MSDS) for compliance and safety purposes.
