<p><P>PROBLEM TO BE SOLVED: To provide a method capable of sufficiently adsorbing halogen based gas even when an adsorbent is dried, and a device. <P>SOLUTION: The treatment method for the halogen based gas has a step for contacting the halogen based gas with NaHCO<SB>3</SB>; and a step for adsorbing the halogen based gas to a Ca(OH)<SB>2</SB>based adsorbent. In the treatment device for the halogen based gas, a column filled with a mixture of NaHCO<SB>3</SB>and the Ca(OH)<SB>2</SB>based adsorbent and a column filled with an NaHCO<SB>3</SB>layer in the upstream side and a Ca(OH)<SB>2</SB>based adsorbent layer in the downstream side are provided. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
