Abstract

The possibility of using coprecipitation on Cu(OH)₂·nH₂O and Fe₂O₃·nH₂O precipitates to separate a part of zirconium unreacted with complexone in the presence of a 100-fold amount of impurities has been examined. The reaction between ethylenedia-minetetraacetic acid (EDTA) and zirconium 10⁻³−10⁻⁵ M has been used as substoichiometric reaction. A zirconium determination in the concentration range of 10⁻⁴−10⁻⁶ g/ml in artificial mixtures and steel samples has been developed using the systems of EDTA-Zr−Cu(OH)₂·nH₂O and EDTA−Zr−Fe₂O₃·nH₂O.
