What Is ASTM D4607 Activated Carbon Iodine Number?
ASTM D4607 determines the iodine number of activated carbon, which indicates its adsorption capacity and micropore content. The test measures how much iodine is adsorbed by the carbon under specified conditions, reflecting its surface area and effectiveness.
This method is widely used in the water treatment, environmental, and chemical industry to evaluate activated carbon used in filtration and purification systems. The iodine number is a key quality parameter that helps assess performance in removing contaminants and improving adsorption efficiency.

ASTM D4607 Activated Carbon Iodine Number FAQs
ASTM D4607 is used to determine the iodine number of activated carbon, which reflects its adsorption capacity and micropore structure, helping evaluate its effectiveness in filtration and purification applications.
The iodine number indicates the amount of micropores and surface area available for adsorption, directly affecting the carbon’s ability to remove contaminants from liquids and gases.
A higher iodine number indicates greater adsorption capacity and higher micropore content, making the activated carbon more effective for removing small molecular contaminants.
Iodine number is an indirect measure of surface area, particularly micropores, which are critical for adsorption of small molecules.
The test mainly reflects micropore adsorption and may not fully represent performance for larger molecules, requiring additional tests for comprehensive evaluation.
ASTM D4607 determines the iodine number of activated carbon to assess its relative activation level and porosity. The result is expressed as milligrams of iodine adsorbed per gram of carbon, helping evaluate its adsorption capacity.
ASTM D4607 involves mixing a standard iodine solution with different amounts of activated carbon, filtering the mixtures, and measuring the remaining iodine by titration. The results are used to calculate the iodine number, which indicates the carbon's relative porosity and activation level.
