摘　　要：为了处理港口码头薄油膜污染,在氩/氢气氛下利用电弧法制备Fe0.64Ni0.36为主相的合金纳米产物,采用水热法和高温碳化法制备碳包覆的核壳磁性FeNi@C/Cu复合纳米颗粒.对合金粒子以及碳包覆后的复合纳米颗粒进行表征及性能检测.结果表明:FeNi合金纳米粒子呈球状,500℃下制得的粒子饱和磁化强度最高,可以达到101.09 A·m2/kg,比常温下制备的粒子提升16.0%.利用FeNi@C/Cu复合纳米颗粒对煤油、柴油与机油的除油能力分别为3.18、3.43和3.46 g/g,表明FeNi@C/Cu复合纳米颗粒具有良好除油性能.In order to deal with the pollution of the thin oil film of port terminal,an electric arc method was used to prepare alloy nanopowder products with Fe 0.64 Ni 0.36 as the main phase in an argon/hydrogen atmosphere.The core-shell magnetic FeNi@C/Cu composite nanoparticles were prepared by hydrothermal and high temperature carbonization methods.Alloy particles and carbon-coated composite nanoparticles were characterized and their properties were tested.The results show that FeNi alloy nanoparticles are of spherical shape.The saturated magnetization value of the nanoparticles prepared at 500℃is of the highest value,reaching 101.09 A·m 2/kg,which increases by 16.0%compared with that prepared at room temperature.The FeNi@C/Cu composite nanoparticles are tested for the adsorption of kerosene,diesel and engine oil,and the adsorption capacities are 3.18 g/g,3.43 g/g and 3.46 g/g,respectively,indicating that the FeNi@C/Cu composite nanoparticles have good degreasing performance.
