Abstract

|
|
1-eicosylsulfate(C20H41SO4-) was coated onto 5 μm C18 reversed phase column. Adsorption equilibrium was reached when 1.2l of 1.46 × 10-4M in 25% acetonitrile solution passed through the column. This coated column proved to be stable up to 10l of 0.05 M α-HiBA eluent used. The column efficiencies of Eu, Nd, Ce and La measured were about 0.04 mm of HETP using 0.15M α-HiBA eluent at a flow rate of 1.Oml/min. This column was used to separate some lanthanides and transition metal ions, andmshowed an excellent resolution, respectively.
