Abstract

N-(amino-ethyl)-amino-propyl trimethoxy silane (AEAPTMS) is used to modify Fe3O4 with a one-pot coprecipitation method. Powder X-ray diffraction measurements show the spinel structure of magnetite nanoparticles. A high positive charge of +33.96mV was obtained on the surfaces of modified magnetic nanoparticles, with the diameter ranging from 6.5 to 22.5 nm. The modified Fe3O4 was first applied to the treatment of wastewater from tertiary oil recovery. The obtained results indicated that the oil removal rate increased with the dosage of modified Fe3O4 and slightly increased with the separation time. The mechanism of modified Fe3O4 toward wastewater from tertiary oil recovery was attributed to the electrostatic interaction between negatively charged microemulsion oil in wastewater and the positively charged surfaces of magnetic nanoparticles.
