Abstract: According to a first aspect of the present invention, provided is a method for recovering a waste potassium iodide solution, the method for recovering an iodide solution comprising the steps of: cooling a waste potassium iodide solution at temperatures higher than a freezing point or at room temperature; filtering foreign materials from the waste potassium iodide solution using a separation membrane module; and concentrating the waste potassium iodide solution filtered in the separation membrane module using a reverse osmosis membrane. The present invention, as configured above, can remove foreign materials included in the waste potassium iodide solution using a decompression-type separation membrane and the waste potassium iodide in which the foreign material is removed can be concentrated by the reverse osmosis membrane to be recycled.
