Dechlorination reactions at sp(2) C-Cl bonds by a pentaphosphino zero-valent iron (ZVI) complex are proposed to follow an oxidative addition, β-Cl-elimination pathway en route to iron-chloride, iron-hydride and iron-acetylide products, the distribution being dependent on the nature of alkyne produced.

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnet...

in this study, magnetic iron oxide nanoparticles (fe3o4) with the size range of 20-30 nm were prepared by the modified controlled chemical co-precipitation method from the solution of ferrous/ferric mixed salt-solution in alkaline medium. in this process polyethylene glycol was used as a surfactant to prevent the solution from agglomeration. the prepared magnetic nanoparticles were characterize...

Immobilizing of zero-valent iron in mono- and bi-metallic systems on the bentonite clay surface as new nanocatalyst were synthesized and used to degrade model acidic dyes from aqueous media. The Fourier-transform infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis were ...

Textile industries are hailed as one of the major environmental polluters in world, owing to their release undesirable dye effluents. Synthetic dyes do not adhere fabric firmly and released into aquatic ecosystem effluent. Consequently, consistent wastewater from numerous textile without previous treatment has detrimental effects on human health. Treatment methods currently being used fail degr...
