FeIII x SnII y SnIV1−x−y H n [P(Mo3O10)4]·xH2O new nano hybrid, for effective removal of Sr(II) and Th(IV)

Abstract

A new FeIII x SnII y SnIV 1-x-y H n [P(Mo 3 O 10 ) 4 ]Á xH 2 O 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.

Anchoring of CoHFC nanoparticles on clinoptilolite for remedy of nuclear wastes

“…Clinoptilolite with the ideal formula of (Na, K) 6 Si 30 Al 6 O 72 .nH 2 O is the most common nat u ral ze o lite found mainly in sed i men tary rocks of vol ca nic or i gin [24]. The XRD pat tern of CoHCF mod i fied ze o lite in ad di tion to the char ac ter is tic peaks of clinoptilolite shows char ac ter is tic peaks at 2q = 40°, 50°, and 55° cor re spond to 420, 422, and 440 plane of the crys tal struc ture of co balt hexacyanoferrate (JCPDS card no: 46907) [27].…”
