Abstract

PURPOSE: To enhance the separation efficiency in a method of separating rare earth elements using a complexing agent and a granular cation exchanger by specifying the volume voids of said exchanger.
CONSTITUTION: When rare earth elements are chromatographically separated by adsorption development using a complexing agent and a granular cation exchanger, a granular cation exchanger having 0.5W0.88 volume voids is used. In case of <0.5 volume voids, the diffusion coefft. of rare earth element ions in the exchanger is hardly increased, and a sufficient separation effect is not produced. In case of >0.88 volume voids, an increase in said diffusion coefft. is weakened, and the amount of ions adsorbed is suddenly reduced to lower the separation efficiency on the contrary. The volume voids Rv is represented by the equation (where Sv is the volume of the resin and Pv is the internal pore volume of the resin), which are obtd. by measurement.
