Title : Synthesis of functionalized magnetite nanoparticles and their integration with low salinity water and surfactant solution

Abstract:

Reduction in interfacial tension (IFT) values between oleic and aqueous phases is recognized as a significant mechanism for oil recovery. It has been wellestablished that surfactants strongly affect the IFT behavior. The effect of nanoparticles (NPs) in combination with surfactants for reducing the IFT has been also investigated. However, the literature still suffers from the lack of enough knowledge about the performance of metal oxide NPs, especially magnetic NPs.

In this study, citric acid-coated magnetic (CACM) nanoparticles (NPs) were synthesized and utilized as an interfacial tension (IFT) reduction agent. Meanwhile, CACM NPs indicated a very significant capability to reduce the IFT value down to 3.9 mN/m without using any surfactant. The CACM NPs, among the other NPs used in this study, have shown a key role in IFT reduction due to their acidic feature (these NPs were coated by citric acid). Consequently, the combination of the NPs with surfactant at low salinity condition, showed major changes (for Fe2O3 and SiO2 NPs) and very limited changes (for CACM NPs) at the interface as the movement of the surfactants by the NPs to the interface increases the surface-active agents at interface for reducing the IFT. The findings of this study can help to gain a better understanding of the IFT behavior using magnetite NPs in combination with surfactant at low salinity condition.
