GB/T 7702.7-2023 "Test methods for coal-based granular activated carbon - Part 7: Determination of iodine adsorption value" is a standard that provides guidelines for measuring the iodine adsorption value of coal-based granular activated carbon.
The iodine adsorption value is an important parameter used to evaluate the adsorption capacity of activated carbon. It indicates the ability of activated carbon to adsorb iodine molecules from a solution. This value is widely used in various industries, such as water treatment, air purification, and gas separation.
This standard specifies the experimental procedures and equipment required for measuring the iodine adsorption value. It includes the preparation of activated carbon samples, the determination of the iodine concentration in the solution before and after adsorption, and the calculation of the iodine adsorption value.
By following the guidelines in this standard, manufacturers and users of coal-based granular activated carbon can ensure accurate and consistent measurements of the iodine adsorption value. This will help in selecting the most suitable activated carbon for specific applications and ensure the effectiveness of the adsorption process.
Overall, GB/T 7702.7-2023 plays a crucial role in standardizing the measurement of the iodine adsorption value of coal-based granular activated carbon, contributing to the quality control and application of this important adsorbent material.
