Abstract

The present invention provides a method for removing iron from an iron-containing solution containing an iron ion, comprising adding a lithium ion battery cathode material containing manganese to an acidic sulfuric acid solution to obtain a cathode material-containing solution, and then precipitating a manganese ion as manganese dioxide in a mixed solution obtained by mixing the iron-containing solution with the cathode material-containing solution while precipitating the iron ion contained in the iron-containing solution as a solid.
