GB/T 12496.7-1999 《Test methods of wooden activated carbon--Determination of pH》 Related products
This standard specifies a method for the determination of the pH value of wood activated carbon, which is suitable for the pH value analysis of wood activated carbon aqueous extract. The determination process involves boiling the activated carbon sample in water without carbon dioxide, infiltrating and measuring the pH value of the filtrate. This method is simple and easy to implement, with an accuracy of 0.1 pH, and is suitable for the quality control and application evaluation of wood activated carbon in water treatment, Food processing and other fields.
