摘要
Glutardiamidoxime (H2B), a diamidoxime ligand that has implications in sequestering uranium from seawater, forms strong complexes with UO22+. Five U(VI) complexes were identified in 3% NaCl solution. The stability constants and the enthalpies of complexation were measured by potentiometry and microcalorimetry. The competition between glutardiamidoxime and carbonate for complexing U(VI) in 3% NaCl was also studied in comparison with the cyclic glutarimidedioxime ligand (H(2)A) previously studied.
