GB/T 7702.16-1997 standard for the determination of activated carbon pH value of coal particles. The activated carbon sample of coal particles is pretreated to ensure that its state is suitable for testing. The pH value of the sample leaching solution is determined by a specified method, such as using a specific instrument (acidity meter, etc.). The operation steps, instrument calibrate and data processing methods are clearly defined in the process to ensure the accuracy and reliability of the measurement results. This standard provides a key means for the evaluation of activated carbon mass of coal particles, which helps to judge its applicability in different application scenarios. It is widely used in activated carbon production, inspection and related use industries to help mass control of products.
