Impregnated Activated Carbon

Impregnated activated carbon is a specialized variant of activated carbon that is infused with chemical agents to augment its adsorptive performance. The impregnation process entails treating activated carbon with substances including sulfur, potassium hydroxide (KOH) and silver, yielding products such as sulfur-impregnated activated carbon, KOH-impregnated activated carbon and silver-impregnated activated carbon. Tailored to adsorb specific contaminants, these modified carbons deliver high efficacy across a wide array of purification scenarios.

Product Introduction

Impregnated activated carbon functions by augmenting the intrinsic adsorptive properties of activated carbon via the incorporation of specific chemical agents. Substances including sulfur, potassium hydroxide (KOH) and silver are infused into the porous framework of activated carbon during the impregnation process. This modification enables the material to target and eliminate specific contaminants with significantly higher efficiency compared to conventional activated carbon.

Various Types of Impregnants
  • Metals/Metal Salts: Silver (Ag) for antibacterial purposes; iodine (I₂) for mercury adsorption; copper oxide (CuO) for desulfurization.
  • Acid-Alkali Reagents: Potassium hydroxide (KOH) for capturing acidic gases (e.g., CO₂, H₂S); phosphoric acid (H₃PO₄) for enhancing organic matter adsorption.
  • Catalysts: Platinum (Pt) and palladium (Pd) for the catalytic oxidation of volatile organic compounds (VOCs).
