Anwendung

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.

Detoxification of Cr(VI) through reduction has been considered an effective method for reclaiming Cr-contaminated soil, sediment, and waste water. Organic matter is widely distributed in soil and aquatic systems; however, low Cr(VI) reduction rates inhibit the adoption of Cr reduction

Phytoremediation has shown great potential as an alternative treatment for the remediation of heavy-metal-contaminated soils and groundwater. However, the lack of a clear understanding pertaining to metal uptake/translocation mechanisms, enhancement amendments, and external effects on phytoremediation has hindered its full-scale

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.

Determination of binding parameters for metal ion binding to proteins usually requires preceding steps to remove protein-bound metal ions. Removal of bound metal ions from protein is often associated with decreased stability and inactivation. We present two simple isothermal titration
