Analysis method of montmorillonite powder

The invention discloses an analysis method of montmorillonite and montmorillonite powder. The method for analyzing the montmorillonite and the montmorillonite powder, provided by the invention, comprises the following steps: measuring the heavy metal content and the adsorption capacity of the montmorillonite and the montmorillonite powder; the heavy metal content determination comprises the following steps: extracting soluble heavy metals in montmorillonite or montmorillonite powder by taking artificial gastric juice as an extracting agent, and analyzing by adopting a plasma mass spectrometer (ICP-MS); the adsorption capacity determination adopts trichloro hexammine cobalt (III) with an ultraviolet absorption effect to detect the adsorption capacity of the montmorillonite. According to the present invention, the adsorption force and heavy metal content analysis method of the montmorillonite and the montmorillonite powder is verified, such that the determination method can be used for product release and stabi
