C18 역상 충전제에 1-eicosylsulfate(C20H41SO4-)를 흡착하는 조건을 조사하였으며 1.46 × 10-4M의 흡착용액(25% 아세토니트릴 수용액) 1.2l를 통과시켰을 때 흡착평형이 일어났다. 이 분리관은 0.05 M α-HiBA용리액 10l까지 안정하였으며 Eu, Nd, Ce , La에 대한 분리관효율은 0.15M α-HiBA 용리액 1.0ml/min에서 약 0.04 mm의 HETP를 나타내었다. 이 흡착분리관으로 희토류 원소 및 전이원소들을 개별 분리하였다.

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.
