The impact of effective parameters such as iron oxide nanoparticles dosage, contact time and solution pH was optimized for removal of Ag(I) and Ni(II) in the nuclear cooling system and the best conditions were compared. Nearly complete removal (97%) of Ni(II) and Ag(I) were obtained at adsorbent dosage of 40 and 20 g/L, respectively. Experiments showed that 4 hours was a good choice as optimum ...

Nickel compounds are carcinogenic to human and are potent inducers of kidney and lung tumors in experimental animals. In this study, the effects of nickel(II) acetate on apoptosis, cell cycle and bcl2 expression in normal rat kidney (NRK- 52E) cells were investigated. Nickel(II) induced apoptosis in NRK-52E cells as demonstrated by DNA laddering. Apparent DNA laddering was observed in cells tre...

BACKGROUND Nickel ferrite, a kind of soft magnetic materials is one of the most attracting class of materials due to its interesting and important properties and has many technical applications, such as in catalysis, sensors and so on. In this paper the synthesis of NiFe2O4 nanoparticles by the hydrothermal method is reported and the inhibition of surfactant (Glycerol or Sodium dodecyl sulfate)...

Abstract A simple analytical method, cheap and biologically friendly, to find Ni (II) in drinking water was developed by dithizone immobilization chloride polyvinyl matrix (PVC) dioctyl phthalate as plasticizers. Nickel is a toxic dangerous metal for humans the environment. The step experimented with making membrane sensor next characterization of UV-Vis spectrophotometry, atomic absorption spe...

In order to investigate whether or not dispersed nanoparticles have an effect of inflammation and fibrosis on animals, we developed a nanoparticle generation system and examined the gene expression of matrix metalloproteinase (MMP) and tissue inhibitor matrix proteinase (TIMP) in rat lung containing inhaled nickel oxide (NiO) or titanium dioxide (TiO(2)) nanoparticles. In both experiments, Wist...

polyimide/nickel oxide (polyimide/nio) nanocomposite was successfully synthesized by sol gel technique, using pyromellitic dianhydriede (pmda), 4,4-oxydianiline (oda) and n,n-dimethylacetamide (dmac) and 10 wt% nickel titanate nanopowders (nps). fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd), scanning electron microscopy (sem), and vibrating sample magnetometer (vsm) we...

Adsorption of Nickel(II) ion onto Activated Carbon prepared from Delonix regia pods activated with Zinc chloride (DRZAC) under various experimental conditions were studied. Batch mode adsorption experiments were conducted. The characteristics of the DRZAC were determined by SEM, XRD, FTIR, BET analysis and pHZPC. The maximum removal efficiency of Ni(II) ion is 85% at pH 6. Under the chosen cond...
