The method comprises the operation steps of sample preparation, sample pre-oxidation and molten glass sheet preparation. Particularly, a hydrogen peroxide solution is adopted to pre-oxidize a sample, and the sample is put into a muffle furnace to be fully oxidized. A mixed solvent of anhydrous lithium tetraborate and lithium metaborate is used for bottoming and covering, a lithium bromide release agent is added, and a molten glass sheet is prepared through high-temperature melting. A new melting sample preparation way is provided for X-ray flu
