In this work, we have examined Ln(III) and MA(III) separation conditions by the extraction chromatography using HONTA adsorbent to decide the Ln(III)/MA(III) separation process fow. From the research results, we found the simulated element of Am(III) for HONTA adsorbent and the conditions to use it. In addition, Ln(III) and Am(III) (simulated element) separation experiments were carried out using the HONTA adsorbent packed column, we have determined the column separation conditions for Am(III) such as order of fow solution and fow rate.
