- Density: Bulk density 0.35–0.55 g/cm3; true density ~2.0–2.2 g/cm3
- Pore structure: Rich micropore, mesopore and macropore structure; large specific surface area (500–2000 m2/g)
- Adsorption performance: Strong physical adsorption capacity for organic matter, pigment, odor, heavy metal ions, residual chlorine
- Hygroscopy: Absorbs water vapor easily under humid conditions, water holding capacity up to 30–60%
- Electrical property: Weak conductivity, good static adsorption effect
- Particle form classification: Powder activated carbon, granular activated carbon, extruded columnar carbon, honeycomb activated carbon
- Thermal property: Non-melting, sublimates at high temperature under vacuum
Chemical Properties
- Main composition: Over 90% elemental carbon, small amount of oxygen, hydrogen, ash metal impurities
- Chemical stability: Stable to dilute acid, dilute alkali, most organic solvents at room temperature
- Combustion characteristic: Burns in air above 350°C to generate CO?; can react with strong oxidants at high temperature
- Surface functional groups: Contains hydroxyl, carboxyl, lactone groups, can produce chemical adsorption with polar substances
- Regeneration performance: Desorption and regeneration can be realized by high-temperature roasting, steam activation, chemical washing
- Catalyst carrier property: High specific surface area can load metal ions, used as catalyst support
- Reductivity: Weak reducing property, can reduce partial metal ions in solution
- Compatibility: Inert with most raw materials; avoid long-term mixing with strong oxidants (potassium permanganate, hydrogen peroxide)
