A vital component of many industries, such as food processing, air filtration, water purification, and chemical manufacturing, is activated carbon. Its quality, which affects adsorption capacity, durability, and performance, has a significant impact on its effectiveness. We'll go over important techniques in this blog for evaluating activated carbon quality so you can choose the best product for your requirements.

1. Iodine Number: Measuring Adsorption Capacity
One of the primary markers of activated carbon's ability to adsorb substances is the iodine number. It provides an indication of how efficiently it can catch tiny molecules by measuring the quantity of iodine (in mg) absorbed per gram of carbon. For uses like gas filtration and water purification, this characteristic is essential.
- Procedure for Testing: Mix an iodine solution at a predetermined concentration with an activated carbon sample.
- Titration: Can be used to ascertain the amount of iodine adsorbed once equilibrium has been attained.
- Optimal Value: Iodine numbers for premium activated carbon should range from 900 to 1100 mg/g.
2. Moisture Content: Ensuring Efficiency
Since water molecules can fill the holes required for adsorption, the amount of moisture in the material has an impact on the activated carbon's capacity to bind. Excessive moisture content lowers efficiency, particularly in gas and air filtration systems.
- Weigh the carbon sample both before and after drying it in a 105°C oven as part of the testing procedure.
- The moisture content is given by the weight difference.
- Optimal Value:Moisture content of high-quality carbon should be less than 5%.
3. Apparent Density: Optimizing Usage
The weight of activated carbon per unit volume is known as its apparent density. It affects the quantity of carbon needed for a given process as well as the price of storage and transportation.
- Procedure for Testing:Add the carbon sample to a container that has been calibrated.
- To find the density in grams per centimeter, weigh the container.
- Perfect Range:For premium carbon, the usual range is 0.4 to 0.5 g/cm³.
4. Ash Content: Ensuring Purity
The quantity of inorganic residue that remains after burning carbon is referred to as ash content. Elevated quantities of ash can hinder adsorption processes and lessen the carbon's efficacy, particularly in applications involving water treatment.
- Testing Procedure: In a muffle furnace, burn the carbon sample at 600°C.
- To find the amount of ash, measure the residue that remains.
- Optimal Value: For most applications, the ash content should be less than 10%.
5. BET Surface Area: Evaluating Porosity
For effective adsorption, activated carbon's surface area is essential. The surface area and pore structure are ascertained by BET (Brunauer-Emmett-Teller) analysis, which has a direct bearing on the carbon's capacity to absorb pollutants.
- Use nitrogen gas adsorption techniques in the testing procedure.
- Determine the surface area by utilizing BET theory to analyze the findings.
- Perfect Range:A quality product will have between 800 and 1500 m2/g of surface area.
6. pH Value: Suitability for Applications
Activated carbon's performance can be impacted by its pH, especially in chemical applications. Choosing a product with the right pH for your purposes is crucial because carbon with the incorrect pH might result in unfavorable chemical reactions.
- Procedure for Testing: Using a pH meter, combine the carbon sample with distilled water.
- Best Value: Ideally, the pH level for general-purpose applications should be between 6 and 8.
7. Abrasion Resistance: Ensuring Durability
Abrasion resistance is a measure of activated carbon's physical strength. The efficiency of carbon particles can be decreased during use and transit as they decompose into dust. The carbon is guaranteed to stay intact due to its high abrasion resistance.
- Use an abrasion testing machine to simulate mechanical stress.
- Measure the weight loss to determine resistance.
- Minimal abrasion loss indicates a durable product.
