FeS particles were synthesized in the solid/liquid interfacial adsorption layer on the surface of highly disperse SiO2 particles, and hydrophobic montmorillonites of lamellar structure. It was established that the presence of nanoparticles can be verified by X-ray diffraction (XRD) and small angle X-ray scattering (SAXS) measurements and their diameter can be determined from the so-called Guinier plot. On the FeS-containing samples, the Mossbauer spectra proved that two components were formed in the studied samples: FeS and FeSO4 · H2O. The Mossbauer parameters showed that Fe2+ has a tetrahedral, rather than an octahedral, environment in FeS.
