description The invention discloses a method for removing metallic potassium from metallic sodium. The method includes the steps that the metallic sodium is mixed and fused with a base solvent, then a potassium removal reagent is added, stirring is continued to make the temperature rises to 100-200 DEG C, stirring reaction is carried out for 4-12 hours, and cooling is carried out to 100-110 DEG C, and stirring is stopped and slowly cooling is carried out to obtain a pure metallic sodium solid; the base solvent is a substance which does not react with the metallic sodium, wherein the boiling point of the base solvent is higher than the melting point of the metallic sodium, and the potassium removal reagent is a substance that reacts only with the metallic potassium, or simultaneously reacts with the metallic sodium and the metallic potassium to form a metallo-organic compound. According to the method for removing the metallic potassium from the metallic sodium, the content of the metallic potassiumcan be reduced to less t
