Updated on February 25, 2026
Characteristics and Challenges: In powdered form, activated carbon is extremely fine, with an average particle size of only 20 microns and a bulk density of 21.5 lb/cu ft (34.4 kg/cu m).
How do you calculate bulk density of activated carbon?
The apparent density, sometimes called the bulk density of activated carbon, or volumetric density is defined as the mass of many particles of the activated carbon divided by the total volume they occupy.
What is CTC in activated carbon?
When comparing air filtration solutions, the industry standard for measuring the efficacy of activated carbon is the carbon tetrachloride (CTC) number. This number describes the internal porosity of materials which is supposed to be an indicator for how effectively it can trap gases.
What is the formula for activated carbon?

What means activated carbon?
Definition of activated carbon : a highly adsorbent powdered or granular carbon made usually by carbonization and chemical activation and used chiefly for purifying by adsorption. — called also activated charcoal.
How do I check the MB value of activated carbon?
After the first 10 ml are decolorized continue to add methylene blue solution (1 ml at a time) till the blue colour disappears for 5 minutes. Decolorizing power of Activated Carbon is expressed in terms of milligrams of methylene blue adsorbed by 1 gram of activated carbon. (This value is MB value).
How can you tell the quality of activated carbon?
There are two approved ASTM test methods. The oven drying moisture determination test method uses the received and dry apparent densities to determine the percent moisture on activated carbon. Oven-drying should only be used when water is the only volatile matter present and when the carbon is not heat sensitive.
How do you measure activated carbon quality?
Iodine Adsorption Test: ASTM D460 is used to measure the slurry phase of activated carbon, which produces numbers of Iodine Adsorption from eight hundred to twelve hundred mg/g. Its number is directly proportional to its capacity. The higher is the number, the greater will be its capacity.
What is CTC adsorption?
The method is basically a measure of the pore volume of the activated carbon and is primarily used as a quality assurance test for the production of activated carbon. …

What is carbons luster?
Steel-gray to black with a metallic luster and a greasy feel. An electrical conductor. Used for high-temperature crucibles, as a lubricant and in “lead” pencils.
1 cubic meter of activated carbon weighs 1 480 kilograms [kg] 1 cubic foot of activated carbon weighs 92.39338 pounds [lbs] Activated carbon weighs 1.48 gram per cubic centimeter or 1 480 kilogram per cubic meter, i.e. density of activated carbon is equal to 1 480 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.
What is the density of activated carbon per cubic foot?
In Imperial or US customary measurement system, the Activated carbon density is equal to 92.393381688 pound per cubic foot [lb/ft³], or 0.855494275 ounce per cubic inch [oz/inch³] .
What is granular activated carbon (GAC)?
The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the “activation” process was applied to charcoal (which had been used for centuries).
What is activated carbon and how does it work?
Activated carbon is a form of graphite that has been processed to create millions of tiny pores between the carbon atoms. This increases the surface area to as much as 300-2,000 m2/g. The increased surface area of activated carbon makes the material suitable for adsorption, a process by which impurities in liquids, vapors or gases are removed.
