<p>PURPOSE:To drastically improve the recovery rate of rhodium at the time of burning and incinerating an aq. org. soln. contg. a rhodium complex to recover rhodium by adding a basic compd. to the soln. CONSTITUTION:A rhodium complex having an org. phosphorus compd. as a ligand is easily obtained from the rhodium complex and org. phosphorus compd. A basic compd. is added to the org. soln. contg. the rhodium complex and org. phosphorus compd., and the soln. is burned and incinerated to recover rhodium. The basic compd. is formed by an alkali and an org. acid (e.g. formic acid, acetic acid, citric acid, etc.). The basic compd. is the oxide, peroxide, hydroxide and carbonate of groups Ia and IIa elements or the sulfide and/or hydroxide of group Ia element.</p> |
