The invention relates to a method for preparing a nanometer nickel pellet with magnetic property. Nickel dichloride, polyvinylpyrrolidone, potassium hydroxide and sodium hypophosphite are dissolved in water respectively; a nickel dichloride solution and a potassium hydroxide solution are mixed, are introduced with nitrogen gas, then added with a sodium hypophosphite solution and continuously keptin a nitrogen introducing state for 10 minutes; the mixed solution is transferred to an inner tank of a hydrothermal kettle with cubage of 15 ml and is continuously introduced with nitrogen gas for protection; the hydrothermal kettle is sealed; the mixed solution reacts for 40 to 60 minutes at a temperature of between 130 and 150 DEG C; and an obtained product is washed by water and ethanol respectively, subjected to magnetic separation and is dried to obtain the nanometer nickel pellet with the magnetic property. The nanometer nickel pellet is subjected to characteristic representation through x ray diffraction (XRD), a transmission electron microscope (TEM) and a scanning electron microscope (SEM); the result shows that the particle diameters of a series of prepared nanometer nickel pellets are between 100 and 500 nanometers; and the particle diameter is relevant to reaction temperature, PH value, dosage of a reducer, reaction time and an added surfactant.
