摘要： An object of the present invention is to provide an operating method which can reduce the amount of silver or mercury dissolved in a solution after contact and can increase the usage of silver or mercury without installing new treating facilities in a process for removing iodine compounds contained in an organic medium, particularly acetic acid or a mixture of acetic acid or acetic anhydride, by contacting them with a cation exchange resin in which at least 1% of the active sites are converted to a silver form or a mercury form. The operating method described above is characterized by carrying out the operation while elevating the temperatures in stages while contacting the organic medium, particularly acetic acid or a mixture of acetic acid and acetic anhydride, containing the iodine compounds with a cation exchange resin.
