The invention relates to a method for extracting rhenium from rhenium-containing smoke tail gas. The technical scheme is as follows: the method comprises the following steps of: introducing the rhenium-containing smoke tail gas which is used as a raw material into an excessive absorbent; separating out supernatant after lots of precipitation is produced; adding an acid solvent the volume of whichis equal to that of the supernatant into the supernatant to obtain feed liquid; heating and boiling the feed liquid; evaporating to remove most of moisture, and then adding a precipitator 4-(2-pyridine azo) resorcinol which accounts for 1 to 3 percent of the weight of the feed liquid, mechanically stirring for 30 minutes, and standing over night; and collecting the precipitation at the bottom, namely an organic rhenium product. The method for extracting rhenium from the rhenium-containing smoke tail gas is simple; and by using the method, the rhenium can be rapidly recovered, and the recoveryrate of rhenium is over 90 percent.
