In this study removal of nickel(II) from aqueous solutions by adsorption on to Palmyra palm fruit seed carbon (PPFSC) and commercial activated carbon (CAC) was investigated as a function of agitation time, pH, and carbon dosage on the adsorption capacity has been studied. The metal adsorption yields increased with the increasing adsorbent dosage and contact time and reached to equilibrium for b...

Nickel compounds are carcinogenic to humans and experimental animals. However, the mechanisms leading to tumor formation are still not understood since the mutagenic potential is rather weak. In contrast, nickel(II) enhances the cytotoxicity and genotoxicity in combination with several other DNA-damaging agents. To elucidate possible interactions with DNA repair processes, the effect of nickel(...

Methyl orange is one dye resulted from the textile industry. The aim of this study is to test theadsorption capacity of nickel oxide nanoparticles for removing the methyl orange from aqueoussolution. The parameters studied were the effect of temperature, contact time and initial pH ofsolution. Results indicate that the removal efficiency of nickel oxide nanoparticles increases withincreasing co...

The goal of this study was to determine the removal efficiencies of chromium, copper, lead, nickel, and zinc from raw wastewater by chemically enhanced primary treatment (CEPT) and to attain a total suspended solids removal goal of 80%. Operating parameters and chemical doses were optimized by bench-scale tests. Locally obtained raw wastewater samples were spiked with heavy metal solutions to o...

The present study was aimed at comparing the ability of three crop plants for phytoremediation of zinc (Zn) and nickel (Zn) from soils. A factorial (3×2×3) experiment based on RCBD was used to compare the treatments, and was repeated three times. The first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (Zn) and nickel (Ni)) and the third factor ...

The Rice Husk Ash is a cheap and readily available biosorbent for the removal of nickel ions from aqueous solutions. This investigation comprises of the equilibrium and kinetics study for biosorption of nickel ions from aqueous solutions using Rice Husk Ash powder as a biosorbent in a batch process. The Rice Husk Ash is obtained from a hotel near Andhra University campus, is dried in sunlight f...

This work investigates heat transfer and phase change during picosecond laser ablation of nickel. In this study, ablation of nickel is studied using a mode-locked 25 ps (FWHM) Nd:YAG laser. The threshold fluence for mass removal (ablation) is experimentally determined. Numerical calculations of the transient temperature distribution and kinetics of the solid–liquid and liquid–vapor phase change...

The important human pathogen Helicobacter pylori requires the abundant expression and activity of its urease enzyme for colonization of the gastric mucosa. The transcription, expression, and activity of H. pylori urease were previously demonstrated to be induced by nickel supplementation of growth media. Here it is demonstrated that the HP1338 protein, an ortholog of the Escherichia coli nickel...

This research work investigates the application of KOH impregnated jackfruit leaf powder to remove Nickel from wastewater. The removal characteristics of Nickel from wastewater was investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showed that the KOH impregnated jackfruit leaf...
