Product Name
Name: Staudenmaier Method of graphite oxide powder
Product Overview
Staudenmaier method is a traditional method used for oxidizing graphite powder. The main steps include: first, mixing natural graphite powder with fuming nitric acid. Then, under stirring conditions, gradually add high concentrations of strong oxidants such as potassium chlorate or potassium permanganate. The reaction is usually carried out at a lower temperature (usually around 0 ¡ãC to control the intensity of the reaction. The advantage of this method is that it can effectively oxidize graphite powder and introduce a large number of oxygen-containing functional groups, such as hydroxyl, carboxyl, and epoxy groups. However, the Staudenmaier method also has some drawbacks. For example, the strong oxidizing agent used in the reaction process has strong oxidizing and corrosive properties, and there is a certain degree of danger in the operation process. The Staudenmaier method, as a classic preparation method, still plays an important role in many fields.
