摘要: A detailed study of isocratic and gradient elution separations lanthanides has been carried out. Analyses industrially scientifically interesting products such as luminescent phosphors have out by with DL-2-hydroxyisobutyric acid. The determination small amounts terbium in gadolinium oxide sulphide is described which an HCl solution was eluted through a stainless steel column packed microparticulate silica, bonded cation-exchange groups. Complete separation achieved. Detection variable wavelength detector following post-column complex formation 4-(2-pyridylazo)-resorcinol monosodium salt. Results obtained on test solutions show good reproducibility sensitivity the method may be considered sufficiently reliable to used routine quality control procedures.
