After our development of an H2saldian molecule which strongest ligand for UO22+ with high selectivity in a marine condition, we attempted its installation into a polymer resin to develop a novel adsorbent was 18.4 g-U/kg-reisn under the seawater condition. Regeneration in 0.1 M HCl(aq) was also successful, facilitating its reuse.
