Nanotechnology is an emerging science offering promising models of decontamination. The present experimental design is to synthesize novel nanoparticles of Iron and Nickel oxides to be used as catalysts for in situ removal of different pollutants discharged from various industries. Particle size of synthesized iron and nickel oxides nanoparticles was characteristic of ~28-36 nm and ~48-56, resp...

in this study metal oxide nano powder namely nio nanopowder was prepared .the producedmetal oxide was characterized and used as potential adsorbent for the removal of pb and zn from aqueoussolution. the rate of uptake of the pb and zn are rapid in the beginning and the time required for equilibrium adsorption is 120 min .the time of equilibrium as well as time required to achieve a definite fra...

Small cation size along with removal of trace iron from the electrolyte solution enables practical use earth-abundant nickel oxide electrodes for selective oxidation organic molecules over water in aqueous solutions.

Nickel resistant bacterial strain Enterobacter asburiae KUNi5 was isolated and showed resistance up to 15 mM and could remove Ni optimally better at 37 degrees C and pH 7. Maximum removal was found at initial concentration of 0.5 to 2 mM, however, growth and Ni removal were affected by other heavy metals. Major amount of the metal was accumulated in the membrane fractions and certain negatively...

groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. this study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...

There has been an increasing trend in the production and consumption of local and imported fruit juices in Iran. The presence of impurities and foreign matter in finished products for human consumption is of great concern because they present health hazards when they exceed beneficial limits. The manufacture of juices requires special attention in terms of purity and the sources of water and it...
