| Abstract: | A column chromatographic method with p-507 resin is proposed for the separation of rare earth elements from the matrix elements Fe, Ti, Mo, etc. in steel. Rare earth elements were desoluted from P-507 resin column with 3. 0 mol/L HC1 solution, then determined by inductively coupled plasma atomic emission spectrometry. |
