Three hydroxypyridinone (HOPO) positional isomers - 1,2-HOPO (L1H) and its water soluble analogue (L1'H), 3,2-HOPO (L2H) and 3,4-HOPO (L3H) have been investigated for the complexation of Zr(iv). Potentiometric and UV-Vis spectrometric studies show a higher thermodynamic stability for the formation of Zr(L1')<sub>4</sub> in comparison with Zr(L2)<sub>4</sub> and Zr(L3)<sub>4</sub> as well as a higher kinetic inertness in competition studies with EDTA or Fe<sup>3+</sup> at a radiotracer concentrat ...[more]
