Method for recovering rhodium from rhodium-containing aqueous solution

The invention relates to a method for recovering rhodium in a rhodium-containing aqueous solution, rhodium in a rhodium-containing acidic solution is precipitated by using a sulfydryl-containing cyclic compound, under the normal pressure condition, heating reflux, stirring and reaction are performed for 0.5-1 hour, the rhodium residual rate of mother liquor is low, and the content of other metal impurities in rhodium precipitate is also obviously reduced. The method not only solves the problem that rhodium is difficult to recover, but also increases production benefits.
