Room-Temperature Synthesis of Ni Nanoparticles as the Absorbent Used for Sewage Treatment

The magnetic Ni nanoparticles of 10–30 nm in size were synthesized by the reduction of Ni2+ by NaBH4 at room temperature. The amount of added water in the formation of Ni nanoparticles is a significant factor, which ensures that Ni nanoparticles are not oxidized by oxygen. XRD patterns and FESEM mic...

Summary:The magnetic Ni nanoparticles of 10–30 nm in size were synthesized by the reduction of Ni2+ by NaBH4 at room temperature. The amount of added water in the formation of Ni nanoparticles is a significant factor, which ensures that Ni nanoparticles are not oxidized by oxygen. XRD patterns and FESEM micrographs showed the constituent and structure and micromorphology. Congo red was used as adsorbate to quantitatively examine the adsorption capability of Ni nanoparticles for the organic dyes in industry wastewater. The magnetic hysteresis measurement indicated that the Ni nanoparticles presented ferromagnetic properties. The experimental results showed the as-obtained Ni nanoparticles might be a potential adsorbent in sewage treatment process.
