Novel combustion synthetic route for the synthesis of nanosized SnO2 is reported. X-ray, tap and powder densities of SnO2 are calculated. Adsorption of Pb2+ ions on combustion derived nanosized SnO2 is studied. The as synthesized SnO2 and lead ions adsorbed SnO2 are characterized by X-ray diffraction (XRD), scanning electron micrograph (SEM), and infrared spectroscopic (IR) techniques. The eluent is characterized by atomic absorption spectroscopy (AAS) and solution conductivity (SC) to know the reduction in the concentration and increase in conductance of lead solution after adsorption on the SnO2 surface. The potential use of solid adsorbents for the adsorption of heavy metal pollutants is envisaged in the present work.

The synthesis of ultrafine MoO3 through a self-propagating combustion route employing polyethylene glycol as fuel is reported. The precursor molybdenum oxalate is employed in this study for the conversion of the precursor to ultrafine MoO3 particles. The solvent casting method is adopted for the synthesis of MoO3 dispersed polyvinyl alcohol nanostructured film (MoO3–PVA). These synthesized MoO3 and their composite samples are characterized for their structure, morphology, bonding and thermal behaviour by XRD, SEM, IR and DSC techniques, respectively. The distribution of MoO3 in polyvinyl alcohol gives a crystalline polymer, a compact structure and an increase in glass transition temperature.

New combustion synthetic route for the synthesis of nanosized 𝛾-Fe2O3 by microwave-assisted route is reported. X-ray density, tap density and powder density of prepared 𝛾-Fe2O3 are calculated. Adsorption study of Pb2+ on combustion derived nanosized 𝛾-Fe2O3 is studied by dynamic method. The 𝛾-Fe2O3 structure and lead adsorbed 𝛾-Fe2O3 (Pb-𝛾-Fe2O3) are studied by X-ray diffraction (XRD). Additional lead peaks in Pb-𝛾-Fe2O3 sample pattern confirm the lead adsorption. Morphology of as prepared 𝛾-Fe2O3 and Pb-𝛾-Fe2O3 is studied by scanning electron micrograph (SEM) technique. Varied morphology for Pb-𝛾-Fe2O3 compared to its 𝛾-Fe2O3 is observed. Variation of bonding in Pb-𝛾-Fe2O3 sample due to lead adsorption is viewed by infrared spectroscopic (IR) technique. Energy dispersive X-ray microanalysis (EDX) is scanned for the lead adsorbed 𝛾-Fe2O3 to know the presence of lead on 𝛾-Fe2O3 surface. The eluent lead solution is characterized by atomic absorption spectroscopy (AAS) and solution conductivity (SC). Reduction in the concentration and increase in conductance of eluent lead solution is observed. The potential use of solid adsorbents for the adsorption of heavy metal pollutants is envisaged in the present work.

The self-propagating low-temperature combustion method was used to produce nanocrystalline particles of zinc ferrite. The products were characterized for chemical and phase composition, morphology and magnetic properties. The results obtained showed the formation of single-phase zinc ferrite nanoparticles with an average particle size of about 40 nm. As-synthesized powder displayed good magnetic property. Due to the simplicity and low cost of this process, it could also become a valuable starting point for the generation of other mixed and complex ferrites.
