Although heavy metals are typically found in trace levels natural waterways, most of them hazardous to human health and the environment, even at extremely low concentrations. Nanotechnology nanomaterials have gained great attention among researchers as a sustainable route addressing water pollution. Researchers focus on developing novel that cost-effective for use water/wastewater remediation. ...

The effective removal of heavy metals from industrial wastewater is the most important issues for many industrialized countries and it is big challenge for human being. This research focuses on understanding adsorption process and developing a cost effective technology for treatment of heavy metals-contaminated industrial wastewater. In this investigation the Fe2O3 magneti...

The contamination of drinking water with naturally occurring arsenic is a global health threat. Filters that are packed with adsorbent media with a high affinity for arsenic have been used to de-contaminate water - generally iron or aluminium oxides are favored materials. Recently, nanoparticles have been introduced as adsorbent media due to their superior efficiency compared to their bulk coun...

BACKGROUND Chromium (VI) has toxic and carcinogenic effects. So, determination and speciation of chromium in environmental samples is very important in view of health hazards. In this study, solid phase extraction (SPE) based on bulky amine-functionalized bimodal mesoporous silica nanoparticles (NH2-UVM-7) as a novel nanoadsorbent was applied for preconcentration and speciation of chromium (III...

toluene and benzene were eliminated using multi-walled carbon nanotubes (mwcnts). in order to investigate influence of acid treatment on the mwcnts adsorption capacities, the mwcnts were functionalized by nitric acid (10 m) under reflux conditions for 2 h. fourier transform infrared (ftir) and raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes surfac...

For the adsorption of copper (II) and zinc ions from polluted water, an efficient inexpensive nanoadsorbent; nickel ferrite-modified montmorillonite nanocomposite was synthesized by co-precipitation mechano-chemically modified with salts iron. The natural MMT, (NiFe2O4-Mod MMT) nanoadsorbent were characterized several techniques including Fourier transform infrared spectroscopy, X-ray diffracti...

Nanoparticles of titanium diboride (TiB2) coated with a conductive polymer and subjected to an oxidizing agent was carried out in this research. TiB2 nanoparticles polypyrrole (PPy) were studied using XRD TEM techniques. Nitrogen adsorption desorption properties are covered modified understand better the surface zone, structural features, pore geometries nanoparticles. The water-based hazardous...
