When a mixture of lanthanoid ions was chromatographed on a filter paper disk impregnated with oxine by dilute acetic acid saturated with phenol and oxine, it was supposed that a oily hydrophobic phase was gradually formed over the surface of the impregnated oxine. Therefore, some extraction chromatographic partition between the oily hydrophobic phase and the developer should be expected. This study was undertaken to confirm the separation mechanism. The result of batch experiments suggested that a mixture of four ions from La to Nd would be successfully separated by [0.5% acetic acid solution saturated with phenol and oxine, a mixture of five ions from Nd to Tb by 1% acetic acid solution saturated with phenol and oxine, and a mixture of seven ions from Tb to Lu by 2% acetic acid solution saturated with phenol and oxine. The results obtained here are consistent with the chromatographic performance of the impregnated filter paper.
