Iodine Number vs BET Surface Area: How to Technically Evaluate Activated Carbon Quality
Key Highlights The iodine number (ASTM D4607) measures micropore adsorption capacity in mg/g and is the fastest field-usable quality test for activated carbon. BET surface area measures total internal surface in m2/g using nitrogen adsorption and provides a complete...
Coconut Shell vs Coal-Based Activated Carbon: A Technical Comparison for Industrial Buyers
Key Highlights Coconut shell carbon is predominantly microporous with hardness numbers of 97 to 99+, making it the top choice for potable water and gold recovery applications. Coal-based carbon has a broader pore size distribution with significant mesopore content,...
