Embodiment Construction
[0006] Raw materials include Fe 3+ Soluble salt, Fe 2+ Soluble salts, anionic surfactants and mixed solvents, mixed solvents are prepared from water-miscible organic solvents, water-immiscible organic solvents and water; mixing and reflux, mixed solvents, Fe 3+ Soluble salt, Fe 2+ Add soluble salt and anionic surfactant into the container, and stir and mix. When the solid matter is completely dissolved and the organic phase immiscible with water turns brown, heat to reflux temperature and reflux for 10min-4h; cool, separate, and wash , dry, stop reflux, cool to room temperature, add separation agent to make Fe 3 o 4 Particles are precipitated, and the Fe 3 o 4 The particles are separated from the solvent, washed and dried in a vacuum oven to obtain fine nanoparticles.
