摘要：

Chromatographic behaviour of the rare earth elements on C-18 bonded silica reversed-phase material has been investigated in aqueous lactate media. The lactatocomplexes of the rare earths are distributed and fractionated on the bonded silica column by a mobile phase gradient technique in the presence of hydrophobic ions. The effects of the lactate concentration pH, methanol and hydrophobic ion concentrations in the eluents have been investigated in detail to have the best resulution of the adjacent rare earth elements. Port-column reaction with arsenazo(III) is used to detect the separated rare earth lactatocomplexes. This reversed-phase partition system is suited to separate and detect all rare earth elements within 40 min with good reproducibility. © 1990 Friedr. Vieweg & Sohn Verlagsgesellschaft mbH.
