Synthesis of NiO using pine as template and adsorption performance for Pb(II) from aqueous solution

Solvothermal synthesis of MnFe2O4-graphene composite—Investigation of its adsorption and antimicrobial properties

“…Pb (II) and Cd (II) ions have been identified as one of the most toxic heavy metal ions due to their detrimental effects on the human nervous system, blood circulation, kidneys and reproductive system. The major sources of lead and cadmium effluent are steel, batteries, thermal power stations and refining industries [5,6]. The guidelines set by World Health Organization (WHO) for metal ions concentration limit is about 0.01 mg L -1 for Pb and 0.003 mg L −1 for Cd ions in drinking water [7].…”

Environmentally Friendly and Controllable Pyrolysis Method to Synthesize Ni-Modified Graphene Nanosheets as Reinforcement of Lead-Free Solder

“…The lattice constant of 0.3515 nm was very close to the theoretical lattice constant of Ni (0.3524 nm); therefore, we can conclude that the flocculent nanoparticles in Figure 4b and the spherical ones in Figure 4c were NiO and Ni, respectively. A large number of nanopores that appeared on the flocculent NiO could be attributed to gas diffusion in the NiO crystal [37].…”

Application of response surface methodology for optimization of Co(II) removal from synthetic wastewater by adsorption on NiO nanoparticles

“…To understand the kinetics of Co(II) adsorption, pseudo first order and pseudo second order models were studied [17,26].…”

“…Nickel oxide has been used for the treatment of Pb(II), Cr(VI), Cd(II), Co(II), Zn(II) and congo red, etc. and it has been proved as a good adsorbent in all cases [13][14][15][16][17].…”
