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.
