A new FeIII x SnII y SnIV1−x−y H n [P(Mo3O10)4]·xH2O nano-hybrid was synthesized by chemical co-precipitation. The product was characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) spectroscopy. From TEM images, the size of the product was estimated to be smaller than 30 nm. The adsorption efficiency of the obtained hybrids were determined for Sr(II) and Th(IV) ions. The kinetics and thermodynamic of metal ions were studied. Results explained that the pseudo second-order sorption mechanism is predominant and the sorption of each ion is an endothermic process.
