Separation of the trivalent actinides from the lanthanides by extraction chromatography

The following conditions were selected for optimum separation of the trivalent lanthanides from the trivalent actinides at room temperature: 10- by 100-mm column of 70- to 80-mesh Tee-Six powder containing 0.45 M HDEHP-heptane as the stationary phase, 0.025 M DTPA in 1 M monochloroacetic acid adjust...

Zusammenfassung:	The following conditions were selected for optimum separation of the trivalent lanthanides from the trivalent actinides at room temperature: 10- by 100-mm column of 70- to 80-mesh Tee-Six powder containing 0.45 M HDEHP-heptane as the stationary phase, 0.025 M DTPA in 1 M monochloroacetic acid adjusted to a pH of 3.0 with NH/sub 4/OH as eluant, and a flow rate of 10 to 12 drops per minute.
