Application
N-(2-Hydroxyethyl)ethylenediamine-N,N′,N′-triacetic acid (HEDTA) can be used as an ionophore for the selective determination of Fe(III) ions by the potentiometric method. It is also used to form complexes with metal ions such as iron(II), copper (II), zinc(II), manganese(II), and uranium(VI) ions. Therefore, HEDTA plays an important role in the separation of f-elements and the treatment and disposal of nuclear waste.

An on-column complexation method has been developed for the simultaneous determination of V(IV) and V(V). Vanadium species were chelated with aminopolycarboxylic acids to form anionic complexes which were separated by capillary zone electrophoresis (CZE) with direct UV detection.
