Fe3O4 nanoparticles have been prepared by the microemulsion technique with water as the aqueous phase, n-hexane as the oil phase and Span 80 as the surfactant. The reaction occurred under air, N2 or high temperature and high pressure atmosphere. Particle size can be controlled by the concentration of the reactants dissolved in water, the ratio of water/surfactant and the atmospheric conditions.

This paper studied the effects of Co, Ni replacement in the Fe1-xCoxFe2O4 and Fe1-yNiyFe2O4 (x, y = 0, 0.05, 0.1, 0.2, 0.5) nanoparticles, pH, weight of nanoparticles/ml of water and time of stirring on the arsenic removal ability. The results showed that small amount of 0.25 g/l of Fe3O4 nanoparticles after stirring time of 3 minutes can reduce the arsenic concentration from 0.1 mg/l to 0.01 mg/l. The removal was also affected by the pH of the water.

Oil absorbent nanocomposites were prepared by suspension copolymerization of laurylmethacrylate (LMA) and styrene (St) with and whithout Fe3O4 nanoparticles and divinylbenzene (DVB) crosslinker. The magnetic composite resin can be recovered after conveniently and rapidly absorbing oil by magnetic separation techniques without excluding other mechanical techniques.

Preparation of stable magnetic nanofluids containing Fe3O4@PPy nanoparticles by a novel one-pot route
Baobao Zhao and Zhaodong Nan*
Abstract Stable magnetic nanofluids containing Fe3O4@Polypyrrole (PPy) nanoparticles (NPs) were prepared by using a facile and novel method, in which one-pot route was used. FeCl3·6H2O was applied as the iron source, and the oxidizing agent to produce PPy. Trisodium citrate (Na3cit) was used as the reducing reagent to form Fe3O4 NPs.
