Product Overview
Activated charcoal AR grade is a highly porous, microcrystalline carbon reagent engineered for exceptional adsorption capacity in laboratory applications. Produced through controlled carbonization and activation processes, this analytical-grade material exhibits a large internal surface area (typically 500-1500 m²/g) that enables efficient removal of organic impurities, pigments, and trace contaminants from solutions. The AR designation guarantees stringent quality control, ensuring minimal ash content (<3%) and absence of interfering substances that could compromise experimental results. Its neutral pH and high chemical stability make it compatible with both aqueous and organic solvents. The powdered form provides rapid adsorption kinetics while maintaining easy filtration characteristics. This reagent undergoes rigorous testing for heavy metals, moisture content, and adsorption efficiency to meet international pharmacopeia standards. The uniform particle size distribution (typically 75-150 μm) ensures consistent performance across different laboratory protocols. Particularly effective for decolorizing solutions, removing odors, and purifying gases, this activated charcoal maintains its adsorption properties across a wide temperature range (20-100°C). The material's hydrophobic surface preferentially adsorbs non-polar organic compounds while repelling water, making it ideal for selective purification processes.
FAQs
1. What is the difference between activated charcoal AR and regular charcoal?
Activated charcoal AR undergoes additional processing to create a highly porous structure with significantly greater surface area (500-1500 m²/g vs 2-5 m²/g in regular charcoal). The AR grade also meets strict analytical purity standards with controlled ash content and absence of impurities that could interfere with laboratory procedures.
2. Can this activated charcoal be used for gas phase purification?
Yes, the high porosity and large internal surface area make this AR grade activated charcoal effective for gas phase adsorption. It can remove volatile organic compounds, odors, and certain gaseous impurities when used in appropriate filtration systems.
3. What is the typical pH range of this activated charcoal?
This analytical reagent grade activated charcoal maintains a neutral pH between 6.5-7.5 when suspended in water, making it suitable for most laboratory applications without affecting solution pH.
4. How should activated charcoal be stored to maintain its properties?
Store in a tightly sealed container in a cool, dry place away from direct sunlight and sources of moisture. Exposure to humidity can reduce its adsorption capacity over time.
5. What particle size range does this activated charcoal fall under?
The powdered activated charcoal typically has a particle size distribution between 75-150 microns, providing an optimal balance between surface area and filtration characteristics for most laboratory applications.
