Research Abstract

Mixed solution of cerium, europium and neodymium was fed to a column packing silica beads which supported bis(2-ethylhexyl) phosphate. The absorption band formed in the column was pushed out with nitric acid solution, and fractionated using a fraction collector. The concentration data analyzing the fraction shows that, although the separation factor was not so high, the elements were separated each other.
