The effect of particle size change of TEHDGA and HONTA impregnated adsorbents on the adsorption performance of MA(III) was evaluated for the establishment of MA(III) separation and recovery technology from high-level radioactive liquid waste by extraction chromatography. From the results of this study, it is clear that impregnated adsorbent with a particle size of approximately 200 μm is suitable for this method in terms of separation, DF, etc.
