Magnetic iron oxide nanoparticles have numerous applications in the biomedical field. This paper reports the preparation and properties of iron oxide nanoparticles synthesised by thermal decomposition method from iron chelates. The iron oxide nanoparticles were characterized by FTIR, powder XRD, VSM, SEM and TEM techniques. FTIR and powder XRD studies show that iron oxide was fo...

The coprecipitation of U (VI) with iron corrosion products from aqueous solutions by zero valent iron was investigated. The evidence of coprecipitation was demonstrated by conducting experiments with well characterized scrap iron, pyrite and a mixture of both materials with experimental durations of up to four months. Results indicate that under anoxic conditions only less than one tenth of the...

background: removing heavy metals from industrial wastewaters by iron nanoparticles has been much noticed in the recent years. chromium is considered as one of the emphasis environmental pollutants. there are high concentrations of chromium in the wastewater of electroplating industries. magnetic iron nanoparticles are used to control and eliminate the heavy metals from industrial effluents thr...

iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. magnetic properties of nanoparticles were measured by vsm. the effect of rea...

in this report, magnetic iron oxide nanoparticles were synthesized via coprecipitation of fe2+ and fe3+ with ammonium hydroxide, and the surface of synthesized nanoparticles was organically functionalized by commercially available amine coupling agent namely, 3-aminopropyl trimethoxysilane (apts) by using well-known sol–gel method. further reaction of the synthesized fe3o4@apts core-shell magne...
