PCT No. PCT/KR94/00027 Sec. 371 Date Nov. 17, 1994 Sec. 102(e) Date Nov. 17, 1994 PCT Filed Mar. 30, 1994 PCT Pub. No. WO94/22804 PCT Pub. Date Oct. 13, 1994.The present invention discloses a method for removing iodine compounds from acetic acid, in which the iodine compound is removed by using a solid adsorbent in the form of an activated carbon fiber having a large strength, a large bulk density, and a large specific surface, so that the treatment of large amounts should be possible, that the acetic acid should not be contaminated during the extraction of foreign materials from the adsorbent, and that the adsorbent can be repeatedly used by regenerating it. The method includes the steps of: preparing a filter in the usual manner by using an activated carbon fiber as the adsorbent; and making acetic acid containing an iodide pass through the activated carbon fiber filter, whereby the iodide in acetic acid is removed by being adsorbed by the activated carbon fiber filter.
