主　　题：Adsorption Re(Ⅶ) Coated Solvent-impregnated resins Alamine 304-1 

摘      要：The recovery of rhenium from waste acid is an urgent issue due to low rhenium concentration and high sulfuric *** solve the problem,novel coated solvent-impregnated resins consisting of inert resins LS-300,Alamine 304-1 and the PVA film(304-CSIRs)were prepared for the separation of Re(Ⅶ)from high sulfuric acid *** was shown that the PVA film coated completely on the surfaces of LS-300 resins with a thickness of 5μm,and Alamine 304-1 distributed completely inside the porous of LS-300 *** adsorption fitted well with Langmuir model and pseudo-second-order model with the saturation adsorption capacity of139.40 mg·*** maximum separation factor of Re(Ⅶ)versus Cu(Ⅱ)was up to 483,and 304-CSIRs had no adsorptions for As(V).The adsorption capacity of Re(Ⅶ)onto 304-CSIRs maintained in 97.79%at the fifth adsorption-desorption cycle.99.87%of rhenium was recovered by 304-CSIRs from waste acid generated from a copper smelter.
