摘 要：<正> Separation of rare earths was investigated by extraction chromatography where H（DEHP）wasused as a stationary phase,while HCl and H2SO4 solutions as a mobile phase.The average separation fac-tors of rare earths,βHCl and βH2SO4,are 3.79 and 4.57.respectively.The βLaCe in HCl and H2SO4 systems areas high as 28.5 and 26.3,respectively.The elution acidity in the study can be down to one tenth and one four-teenth of that in HEH（EHP）system.
