Product Overview

Activated Charcoal Powder (CAS No. 7440-44-0) is a porous carbonaceous adsorbent produced by treating carbon-rich material to develop an extensive internal pore structure and a large surface available for adsorption. Unlike absorption into the bulk of a material, activated charcoal primarily retains substances at its surface and within its pores. This characteristic enables it to remove selected dissolved or dispersed impurities from liquids and gases through surface interaction.

The powdered form provides effective contact with the material being treated and is particularly suitable for laboratory purification, clarification, and decolourisation procedures. Its adsorption behaviour depends on factors such as pore structure, surface chemistry, particle size, contact time, and the nature of the substance being removed. Product suitability and the required quantity should therefore be established according to the specific laboratory process and applicable product specification.

Typical Applications

• Decolourisation of laboratory solutions and reaction mixtures
• Adsorptive removal of dyes, coloured compounds, and selected organic impurities
• Purification and clarification during chemical preparation and synthesis
• Treatment of liquid samples before further processing or analysis
• Adsorption studies involving dissolved organic substances
• Laboratory-scale water and wastewater treatment investigations
• Preparation of purified intermediates and process solutions
• Research involving porous carbon adsorbents and surface adsorption

Powdered activated carbon is widely used as an adsorbent for organic compounds and colour- or odour-producing substances in aqueous treatment and purification processes.

Storage Conditions

Store in a tightly closed container in a cool, dry, and well-ventilated place. Protect from moisture, contamination, and incompatible oxidising materials. Keep the container securely closed after use to preserve the adsorption capacity and prevent the powder from taking up substances from the surrounding atmosphere.
