In the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM...

The uptake of REEs was investigated using nano-zero valent iron (nZVI) and alumina-supported nZVI (AlnZVI). The results indicated fast uptake, with saturation approached within 10 min of contact between solutions and solids. Upon using nZVI, the uptake of REEs seemed to be quantitative over the studied range of concentration; 1.0–100.0 mg L . When Al-nZVI was used, complete removal was achieved...

Nanoscale zero-valent iron NZVI particles were synthesized by the aqueous phase borohydride reduction method, and the synthesized NZVI particles were used for the degradation of Basic Yellow 28 BY28 dye in aqueous solution. The influence of experimental variables such as reaction time, NZVI particle dosage and pH were studied on the decolorization of BY28. Mixing an aqueous solution of 100 mg L...

Rapid population growth has evolved the big problem of limited fresh water supply in the world and the wastewater treatment is the only recycling process which can overcome this problem. Technology advancement has led us to the nanotechnology which is having tremendous scope for wastewater treatment. Nanoadsorbents, magnetic nanoparticles, nanofiltration, nano zero valent iron, nanocatalysts, n...

Nanoscale Zero Valent Iron (nZVI) represents a promising material for subsurface water remediation technology. However, dry, bare nZVI particles are highly reactive, being pyrophoric when they are in contact with air. The current trends of nZVI manufacturing lead to the surface passivation of dry nZVI particles with a thin oxide layer, which entails a decrease in their reactivity. In this work ...
