Abstract
A method of separating iodine gas by passing a phase containing iodine gas through a hydrophobic separation membrane containing pores having a pore diameter of 1 nm to 60 .mu.m, retaining iodine gas on the upstream side of the flow of the phase in the separation membrane, and removing the phase from which iodine gas has been removed from the downstream side of the separation membrane. In addition, a membrane that is impermeable to water but permeable to steam is used in combination with this separation membrane.
