US20150041399A1 Ferrous Nanoparticle Oil Extraction Ferrous Nanoparticle Oil Extraction is the process of introducing ferrous nanoparticles coated in an oleophilic surfactant into oil reservoirs and implementing a magnetic force within the oil to supplement the traditional suctioning forces to extract oil. The nanoparticles, once in the oil, are allowed to disperse by Brownian motion and bind to the oil particles.Magnetic alginate–Fe3O4 hydrogel fiber capable of The magnetic Fe3O4 nanoparticles used in this study were synthesized using a conven magnetic alginate–Fe 3 O 4 hydrogel fibers can work as a simple and costeffective probe for the successful adsorption/separation of behaviour when studied with the help of a vibrating sample magnetometer and can be easily separated using a strong magnet.

Preparation and characterization of chitosan‐siloxane The mixture was added dropwise slowly to 500 mL of NaOH solution (1 N) under vigorous stirring using hotplate with magnetic stirrer until the magnetic nanoparticles were obtained and precipitated (Figure 1). Finally, the magnetic nanoparticles were recovered by magnet, washed five times with deionized water, and dried in oven at 70°C.Potential appliions of magnetic nanoparticles within Cited by: 9
Synthesis of Stable Iron Oxide Nanoparticle Dispersions in separation of nanoparticles. Also, the efficiency of separation by a strong magnet was too low to have a good separation. The small size of nanoparticles and functionlisation with surfactants show a great resistance of nanoparticles against separation by a centrifuge or magnet [23].Laccase biosensor using magnetic multiwalled carbon collected by a permanent magnet separation and then washed with distilled water until the solution approached to be neutral and dried with a vacuum freezing dryer

Separation of Fe3O4 Nanoparticles from Water by The initial sedimentation rate of the nanoparticles in water and under magnetic fields is higher for less concentrated suspensions (c 0 = 0.1 g/l) than for more co ncentrated ones (c 0 = 1 g/l). This might be connected with the formation of gel structures due to strong magnetic attraction between ferromagnetic nanoparticles.Highgradient magnetic separation of coated Translate this pageHighgradient magnetic separation of coated magnetic nanoparticles_电子/电路_工程科技_专业资料 12人阅读次下载 Highgradient magnetic separation of coated
