STUDIES ON THE EXTRACTION OF Re(Ⅶ)WITH QUATERNARY AMMONIUM SALT N263 AND TOA
Abstract:
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 K1,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 K1,n the equilibrium constant,n=0,1 for N263 and n=0,1,2 for TOA.
