【 摘 要 】

This work reports on employment of Lanthanum (La) substituted Manganese-Zinc (Mn-Zn) ferrite (MnZnLaxFe2-xO4) nanoparticles (NPs) for enhance oil recovery (EOR) applications. MnZnLaxFe2-xO4 NPs with different La concentration were synthesized by using sol-gel auto-combustion method. The best magnetization parameters can be achieved at La composition, x = 0.08 with the highest value of saturation magnetization, remanence and coercivity which are 23.6 emu/g, 7.42 emu/g and 197.7 Oe, respectively. The sample with best magnetization parameters was used in nanofluid under different concentrations. Interfacial tension (IFT) and contact angle measurement for nanofluids were then performed. Increased Mn-Zn ferrite concentration in nanofluid reduced the oil-water IFT and contact angle indicating the increase in oil wettability.
