GB/T 12496.9-2015

This standard specifies the method for determining the caramel decolorization rate of wooden activated carbon, used to evaluate its adsorption performance for colored organic molecules. It is applied in the quality control and testing of wooden activated carbon products, particularly in industries such as food processing, water treatment, and chemical purification where decolorization efficiency is critical. The test is conducted under controlled laboratory conditions to ensure consistent measurement of the carbon's ability to remove caramel-based colorants from solution.
