1. Core Composition & Structure
Zhongci Activated Alumina Adsorbent is a highly porous,amorphous aluminum oxide (Al₂O₃) material engineered for maximum surface area and adsorption capacity. It features a uniform spherical morphology with controlled pore distribution, ensuring optimal contact efficiency with target contaminants.
2. Key Functional Properties
- Superior Adsorption Performance:
- Fluoride Removal: Specifically optimized for efficient defluoridation in drinking water, critical for high-fluoride regions.Trace Contaminant Adsorption: Effective in adsorbing trace pollutants like phosphorus, arsenic, and heavy metals (e.g., Cr(VI)) from water.Gas Purification: Modified variants can treat hydrogen sulfide (H₂S) and other odorous gases.
- High Mechanical Strength & Stability: Maintains structural integrity (no swelling or cracking) even after significant moisture uptake, enabling long-term use in dynamic systems .
- Thermal Resilience: Exhibits excellent stability under high temperatures, supporting applications in catalysis and regenerative processes.
- Regenerability: Can be economically regenerated multiple times through thermal treatment (typically 400–500 K), restoring adsorption capacity.
3. Primary Applications
- Water Treatment:
- Emergency removal of arsenic/fluoride in contaminated water supplies.
- Advanced purification of industrial wastewater (e.g., glyphosate production effluents, cyanide-bearing streams).
- Air/Gas Purification:
- Dehydration of gases (air, natural gas).
- Elimination of acidic gases and volatile organic compounds (VOCs).
- Catalysis: Serves as a robust catalyst support due to its high surface area and thermal stability.
- Specialized Separation Processes: Used in chromatographic separation and targeted recovery of specific ions.
4. Competitive Advantages
- Efficiency: Rapid adsorption kinetics and high contaminant uptake capacity per unit mass.
- Durability: Resists physical degradation under operational stress (flow, pressure, moisture).
- Environmental Safety: Non-toxic, inert, and chemically stable during use.
