Description of the Invention: [Technical Field] The present invention relates to a method for preparing an oily magnetic fluid, which particularly relates to an oily magnetic fluid capable of adsorbing organic substances, oily substances and metal ions in a fluid, and then By the action of an external magnetic field, it is separated from the fluid to achieve treatment or purification for the user. [Prior Art] According to the 'magnetic material, it has been widely used in the past for the preparation of miscellaneous memory materials such as tapes, magnetic disks, and magnetic tapes, and for building materials such as inks, paints, and paints, and electromagnetic switches and shaft seals. In recent years, the neo-instructor's method of preparation, the Xuxiang_Ying (10) domain has also gradually developed, such as the biomedical applications of pharmaceuticals, proteins, and purines, and the treatment of environmental wastes, such as US 4, 687. , 748 (1987) discloses the use of a carbon hydration recording solution towel in which magnetic particles are mixed in a polar phase to prepare a miscellaneous amount smaller than 诵 nm, which can be prepared for fine separation, purification, and the like. Such a technique utilizing magnetic separation can be divided into two types according to the characteristics of the substance to be treated, (1) separating the magnetic substance f itself by using an external magnetic field, and (2) combining the magnetic material (4) with the magnetic material, and then taking care of it. An external magnetic field is recorded. In order for non-magnetic materials to be effectively combined with magnetic materials, the types and preparation methods of different magnetic materials will play an important role. The related magnetic materials 'have different preparation methods depending on the application object and the demand, and the most common ones are (1) mechanical grinding methods'. For example, the US patent us 4 6H 222 (Na) discloses the use of mixed organic carriers such as glycol (glyC〇1), Ester, magnetic particles and cationic surfactants, etc., although the quality of the machine is mixed into frequency, improve the electrical conductivity of the computer _ design and the sealing effect, (2) oxidation reaction, such as the US patent us 614 〇〇〇 1 (Fiber) reveals the use of a ferrous solution (ferr〇us s〇luti〇n) to react with a phthalate compound such as sodium chlorate (Magnesium (10) 咐h〇Ph〇sphate) and an alkali hydroxide to form iron hydroxide (8) Then, oxygen is introduced to carry out the oxidation reaction to generate ferrite magnetic powder. And (3) chemical co-precipitation method, for example, U.S. Patent No. 6, 743' 371 (2GG4) reveals iron oxides such as iron powder and scales, and gold, silver, and 1293075 copper! Conductive particles such as lum graphite are mixed to form a magnetic fluid for use in an electromagnetic switch. Since the magnetic I* particles themselves are attracted to each other and aggregate, the surface treatment of the particles is required during the preparation process, so that the particles can be effectively separated, and the powder having a smaller particle size can be obtained, so that it is easier to disperse in the solvent. Medium fluid state. At the same time, in order to make the prepared oily magnetic fluid have oleophilic or hydrophilic properties, the surface treatment is usually different. For the preparation of oily oily magnetic fluids, U.S. Patent No. 5,124, No. (10) 2) also discloses the use of a low-point organic solvent in an organic dispersant containing a hydrophilic group to disperse magnetic particles therein, and the evaporation method will lower the boiling point. The organic solvent is removed, and the oily magnetic fluid can be prepared to meet the seal design of the real recorder. Another example is the US patent US 6, G68, 785 (2GGG) which reveals the direct mixing of a-Fe2〇3 powder, oil (Ampro Typen〇il) and surfactant (p〇iy〇iefin a_Hde) to form a slurry. The shooting type is made of magnetic. Since the mechanical grinding is directly performed using the magnetic particles, the oil and the interface are on the surface of the leaking particles, and therefore the bonding force to each other is small, the surface-bound substance may be easily peeled off, and the use efficiency may be affected. Magnetic fluids are commonly used in magnetic memory materials and mechanical shaft seal designs in the same industry. However, the removal of oil or trace organic components in water and the treatment of metal ions in inorganic wastewater are less applicable. In the past, wastewater was usually treated by heat treatment or chemical oxidation. The cost is not only cost 3. It requires chemical reagents and there is a problem with secondary wastewater. For the metal ion-containing wastewater, in addition to the conventional dosing and precipitating treatment method, there is also a physical treatment method such as film separation, and although it is not necessary to add a chemical reagent, the required equipment cost is high, and the technical demand is high. In order to make the oil magnetic fluid have an oleophilic interface and a strong binding force with the magnetic oxidized powder, the present invention utilizes a surfactant containing a certain group of functional groups during the preparation of the ferrite metal oxide, so that the two At the same time, the reaction generates a ferromagnetic substance containing a slow-acting functional group, and then reacts with another oil-based substance to form an oily magnetic fluid by using a bridging reaction. Since the magnetic substance forms a lining with the chemical reaction of this compound, it has a strong binding force and a high stability. (§) 6 1293075 SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for forming and controlling the bridging action of a functional group of a aging body, and using the compound--, (4) n i _ can be more effective The material junction causes oily magnetic current to be treated or purified.
