General description

Ethylenediaminetetraacetic acid is a water-soluble chelating agent[1] that can form complexes with metal ions.[2][3]It is useful for metal ion detection and water treatment[4]

Application

Ethylenediaminetetraacetic acid can be used:
  • As a chelating agent in the preparation of ferromagnetic BiFeO3 nanoparticles by sol-gel process.[5]
  • As a mobile phase in chromatographic separation of rare earth elements.[6]
  • To functionalize the Au nanoparticles, which are used as probes in the colorimetric estimation of chromium(III) ions in solution.[7]
