The incorporation of some of these metals during Fe(II) oxidation-induced precipitation at moderate temperatures (80-100°C) appears to be limited, for reasons not fully understood, and to extents not always agreed (e.g., Ni2+, Cr3+). In this paper, the incorporation maxima of six metals into the structure of precipitated ferrites (in terms of x in MexFe3-xO4, Me represents a noniron metal) were concluded to be 1.0, 1.0, 0.78, 0.49, 0.35, and 0.0 for Zn2+, Co2+, Ni2+, Al3+, Cd2+ and Cr3+, respectively. With the exception of the much larger Cd2+, these values were associated with kinetic considerations controlled by the H2O exchange rate between the hydration shells surrounding the dissolved metal ion.en1095-710320111129135CoprecipitationFerriteIon incorporationIsomorphous substitutionSubstituted magnetiteNatural Resources, Energy and EnvironmentChemical engineeringJournal Article10.1016/j.jcis.2011.02.046Journal Article
