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.

Abstract

A fine nano particle preparation technology includes following steps: (1) blending raw materials including a Fe<3+> soluble salt, a Fe<2+> soluble salt, an anionic surfactant and a mixed solvent; (2) reflux: heating the mixed solvent to a reflux temperature with protection by nitrogen and performing the reflux for 10min to 4h; and (3) performing a cooling process, a separation process, a washing process and a drying process, stopping the reflux and cooling the mixture to room temperature, and performing vacuum drying to obtain the fine nano particle. The preparation technology is suitable for factory large-scale production.

Description

technical field [0001] The invention belongs to the technical field of nano new material preparation, in particular to a preparation process of fine nano particles. Background technique [0002] As the frontier of science and technology in the 21st century, nanotechnology is highly sought after by people.
