The extraction of Re(Ⅶ)with quaternary ammonium salt N263 and trioctylamine(TOA) in n-octane from hydrochloride medium has been studied. The experimental results indicate that the extraction mechanism is an anion exchange:ReO₄^-+(n+1)ACl₍₀₎???19870506???ReO₄A·ACL₍₀₎+Cl^- where(0) represents the organic phase and K_1,n the equilibrium constant,n=0,1 for N₂₆₃ and n=0,1,2 for TOA., The extraction of Re(Ⅶ)with quaternary ammonium salt N263 and trioctylamine(TOA) in n-octane from hydrochloride medium has been studied. The experimental results indicate that the extraction mechanism is an anion exchange:ReO₄^-+(n+1)ACl₍₀₎ReO₄A·ACL₍₀₎+Cl^- where(0) represents the organic phase and K_1,n the equilibrium constant,n=0,1 for N₂₆₃ and n=0,1,2 for TOA.
