Volatile hexafluoroacetylacetonates for the isolation and gas-chromatographic determination of trace metals. Pt. 1
Description
The optimization of the extraction of metal cations [Sc(III), Cr(III), Mn(II), Fe(III), Co(II), Cu(II), Zn(II), Y(III), Ag(I), Cd(II), La(IIII), Ce(III), Eu(III), Yb(III), Hg(II), Pb(II), Th(IV), U(IV, VI) and Am(III)] in the form of mixed-ligand complexes with hexafluoroacetylacetone and neutral donators with nitrogen atoms or P=O-groups is described. The thermal and gas-chromatographic characteristics of the extracted volatile compounds are reported. Optimal results were achieved using tri-n-butyl-phosphine oxide as donator. (orig.)
Abstract (German)
Es wird die Optimierung der Extraktion von Metallkationen [Sc(III), Cr(III), Mn(II), Fe(III), Co(II), Cu(II), Zn(II), Y(III), Ag(I), Cd(II), La(III), Ce(III), Eu(III), Yb(III), Hg(II), Pb(II), Th(IV), U(IV, VI) und Am(III)] in Form gemischter Komplexe mit Hexafluoracetylaceton und neutralen Donatoren mit Stickstoffatomen bzw. P=O-Gruppen beschrieben. Ueber thermische und gaschromatographische Eigenschaften der extrahierten fluechtigen Verbindungen wird berichtet. Optimale Ergebnisse wurden mit Tri-n-butylphosphinoxid als Donator erzielt. (orig.)Additional details
