Reduced graphene oxide(rGO)–silver(Ag) nanocomposites have been prepared by using solution based facile one-pot synthesis process. The reaction process involves high-temperature liquid-phase exfoliation of graphite oxide and silver acetate in presence of N-N’dimethylformamide (DMF) solvent, resulting in simultaneous formation of rGO as well as Ag nanoparticles. Different nanocomposites have bee...

In the present work, health risk of heavy metals such as As, Cd, Co, Cr, Cu, Hg, Ni, Pb, Zn in Iranian urban and rural samples including wheat, wheat flour, bread, pasta and sweets were assessed. The real amount of heavy metals in target samples were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and atomic absorption spectroscopy (AAS). Wet ashing and hydride g...

In the framework of the PLAS’STER project, a prototype based on a RF plasma confined inside sterilization pouches for the treatment of medical devices has been developed. In this work, optical emission spectroscopy was used to study the plasma emission from VUV/UV to IR wavelengths range. The results showed the production of strong UV radiation, radicals and atomic species depending on the proc...

A magnetically recoverable catalyst consisting of Mn (III) salophen complex was prepared. The synthesized catalyst was characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), inductively coupled plasma atomic emission spectroscopy (ICP-AES) and Fourier transform infrared (FT-IR). The immobilized catalyst was shown to be an ef...

The article describes a nonlinear theory of how the presence third elements affects results analyzing elemental composition substances by means atomic emission spectroscopy. is based on assumption that there an arbitrary relationship between intensity analytical line analyte and concentration impurities alloying elements. has been tested simulation problem using commercially available equipment...
