摘要：

Rare earth elements in nitric acid solution can be individually separated by ion-interaction chromatography. The separation is achieved by isocratic elution with oxalic acid as the complexing agent in the eluent and tetra-n-butylammonium hydroxide as the ion-pairing reagent. The separated rare earth elements are measured spectrophotometrically after post-column reaction with Arsenazo III, and can be determined at levels greater-than-or-equal-to 0.5 mg/l with a relative standard deviation of 0.01% for the individual rare earth elements at the 10 mg/l level. The order of elution is from lanthanum to lutetium, yttrium being eluted immediately after terbium.
