Charcoal Decolourising Powder Extra Pure is a high-grade activated carbon used in laboratory settings for purification and clarification processes. Its exceptional adsorptive properties make it ideal for removing color impurities, organic contaminants, and unwanted residues from chemical solutions, solvents, and extracts. This extra pure form is especially suited for sensitive analytical work, pharmaceutical preparations, and biochemical applications where high purity and minimal contamination are critical. It is commonly used in filtration experiments and in the refinement of reagents and compounds. The powder should be handled in a dry environment and stored in airtight containers to maintain its effectiveness.
Charcoal Decolourising Powder Extra Pure
Primary Uses
- Adsorption and Purification of Solutions
-
-
- Commonly used to remove colored impurities from chemical solutions by adsorbing dyes, pigments, or decomposition byproducts, especially in organic synthesis and analytical prep work.
-
- Clarification of Organic Compounds
-
-
- Especially effective in purifying recrystallized products like benzoic acid, naphthalene, or acetanilide by eliminating colored contaminants.
-
- Sample Preparation in Chromatography
- Helps pre-clean or decolorize liquid samples before chromatographic separation to avoid interference or streaking on TLC plates or columns.
Secondary Uses
- Demonstration of Adsorption Principles
- Frequently used in teaching labs to show surface adsorption processes, including comparison with other adsorbents like silica gel or alumina.
- Biochemical Preparation Support
- In some biochemical or pharmaceutical lab settings, it can clarify enzyme solutions, vitamins, or alkaloid extracts without affecting activity when used correctly.
- Filtration Experiments
-
- Often combined with vacuum filtration to demonstrate adsorption + separation techniques in lab training.
