PROBLEM TO BE SOLVED: To provide a purification method for simply and efficiently removing, from salts molten at normal temperature, metals such as an alkali metal and a halogen which are contained in the molten salt as impurities.
SOLUTION: The high-purity salt molten at room temperature is obtained by washing, with an acid water-solution or an alkali water-solution, metals such as an alkali metal and a halogen which are contained in salts molten at room temperature as impurities.
