Scope
Scope: This standard specifies the reagents and materials, instruments and equipment, determination steps, and result calculation for the determination of iodine adsorption value of graphene materials. This standard is applicable to the determination of iodine adsorption value of graphene materials; Main technical content: The determination of iodine adsorption value is one of the most common methods for studying and evaluating the adsorption capacity of carbon materials. It has been widely used in the testing of products such as activated carbon and carbon black. Both domestic and international standards have been established, including GB/T 12496.8-2015 "Determination of Iodine Adsorption Value for Wood-Based Activated Carbon", GB/T 7702.7-2008 "Determination of Iodine Adsorption Value for Coal-Based Granular Activated Carbon", and ISO 1304:2016 (en) "Rubber Compounding Ingredients - Carbon Black - Determination of Iodine Adsorption Number". Graphene materials, as a new type of carbon nanomaterial, have the characteristics of a large theoretical specific surface area (the theoretical specific surface area of a single layer of graphene is 2630 m2/g), high adsorption capacity, and rapid adsorption. Therefore, introducing the iodine adsorption value test method into graphene materials is of great practical significance and can be used as a means of evaluating the adsorption capacity of graphene materials, controlling their quality stability, and developing downstream product applications. During the development of this standard, the reproducibility of the physical adsorption capacity of graphene materials with iodine was extensively tested to evaluate the adsorption capacity and quality stability of the materials. For graphene materials containing a small amount of common functional groups such as carboxyl, phenolic hydroxyl, and carbonyl groups, which do not undergo reactions such as iodomethane or halogenation under neutral conditions, this standard is applicable.
