- Scope
The iodine number is a relative indicator of porosity in an activated carbon. It does not necessarily provide a measure of the carbon''s ability to absorb other species. Iodine number may be used as an approximation of surface area for some types of activated carbons (see Test Method ). However, it must be realized that any relationship between surface area and iodine number cannot be generalized. It varies with changes in carbon raw material, processing conditions, and pore volume distribution (see Definitions D2652).
The presence of adsorbed volatiles, sulfur; and water extractables may affect the measured iodine number of an activated carbon.
1.1 This test method covers the determination of the relative activation level of unused or reactivated carbons by adsorption of iodine from aqueous solution. The amount of iodine absorbed (in milligrams) by 1 g of carbon using test conditions listed herein is called the iodine number.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.
