摘要: Abstract Analytical separation of rhenium(VII) is achieved by solvent extraction with N-benzylaniline in chloroform from sulphuric acid media. Few cations interfere: common anions such as phosphate, tartrate, citrate, oxalate, fluoride, EDTA and ascorbic do not interfere. A simple method described for the micro amounts rhenium macro molybdenum, tungsten, niobium tantalum. The also separates V, Cr, Se, Te, Os, Ru, Rh, Pd Pt. molar absorptivity thiocyanate complex butyl acetate diisopropyl ether 40280 ± 280 at 430 nm.
