(Universidade Federal de Santa Maria, 2007-12-03)
In this work, the structures of coordination polymers and molecular compounds Cu(II), Hg(II), Pb(II) and Cd(II) with phenylphosphinate or diphenylphosphinate ligands were determined and are discussed. The reaction of ...
Determinação de alumínio e ferro em fluidos pós-hemodiálise empregando voltametria e decomposição de amostras com radiação ultravioleta
(Universidade Federal de Santa Maria, 2007-10-19)
The simultaneous determination of Al(III) and Fe(III) in post-hemodialysis fluids was investigated by the Adsorptive stripping voltammetry (AdSV) of solochrome violet (SVRS) metal complexes. The analytes build electroche ...
Líquidos iônicos: aplicação na síntese de β-dimetilaminovinil cetonas e na N-alquilação de pirazóis
(Universidade Federal de Santa Maria, 2007-02-15)
The synthesis of two 1-methyl-3-alkylimidazolium tetrafluoroborate (where alkyl = butyl, octyl; [BMIM]BF4 and [OMIM]BF4) based on room temperature ionic
liquids (RTIL) is reported. The usefulness of these ionic liquids ...
