GB/T 6609.35 - 2009 is a standard for the determination of the specific surface area of aluminum oxide, using the nitrogen adsorption method. The standard specifies the preparation of the sample in detail to ensure that the aluminum oxide sample used for testing is representative. There are clear requirements for the nitrogen adsorption equipment and operation process used in the experiment, including the calibrating of the equipment, the control of the test environment, and the specific steps of the adsorption and desorption process. Through this standard, the specific surface area of aluminum oxide can be accurately determined. This data is crucial for evaluating the application performance of aluminum oxide in catalysts, Adsorbent and other fields, helping enterprises to control the product mass and optimize the production process.
