This standard specifies the method for measuring the iodine adsorption value of activated carbon particles from coal, including the test principle, required reagents and materials, equipment, sample preparation, determination steps, data processing, precision requirements and preparation of test reports. It is suitable for the determination of iodine adsorption value of activated carbon particles from coal and Miscellaneous shape activated carbon. The standard covers how to determine the iodine adsorption capacity of activated carbon under specified conditions, that is, the number of milligrams of iodine in activated carbon adsorption under specific test conditions. The reagents used include the chemical reagents muriatic acid, iodine and potassium iodide, and the relevant laboratory water standards and analytical test paper specifications are quoted to ensure the accuracy and Reliability of the determination results.
