Anotace	Controlled thermal decomposition of zinc and iron acetylacetonates in the presence of oleic acid and oleylamine provided surfactant-capped magnetic nanoparticles with narrow size distribution and the mean diameter of ≈15 nm. The combined study by XRD, XRF and Mössbauer spectroscopy revealed: (i) the actual ratio of Zn:Fe was considerably lower in the product compared to the initial ratio of metal precursors, (ii) pure stoichiometric Zn-doped magnetite system with no signatures of oxidation to maghemite was formed, (iii) Zn2+ ions were distributed at both tetrahedral and octahedral sites. Furthermore, carbon-coated nanoparticles were achieved by pyrolysis of the surfactants at 500 °C, providing a potential sorbent of organic pollutants. Preliminary experiments with magnetic solid-phase extraction of β-estradiol from aqueous solutions evidenced applicability and reusability of the carbon-coated product in the separation of steroid pollutants.
