Abstract
The suspended magnetic particle for adsorbing oil in water and its preparation process is disclosed. The suspended magnetic particle is prepared with hollow bead of industrial slag and flyash as carrier, and through depositing ferrite on to the surface to form magnetic particle and surface treatment. It is spread to pollut water to constitute suspended magnetic particle-oil mixing system, and under the action of the magnetic field, the suspended magnetic particle-oil mixing system is controlled to move so as to reach the oil pollution treating aim. The hollow bead has the chemical composition of SiO2 and Al2O3 mainly and has no environmental pollution. The used suspended magnetic particle may be adsorbed, collected and treated properly for reuse.
Description
Technical field
The present invention relates to a kind of control of adsorbing oil dirt on water, suspending type magnetic particle of improvement and preparation method thereof of being used for.
Background technology
In modern society, oil occupies extremely important status as the energy.Yet, in exploitation, processing, transportation and the use of oil, a considerable amount of Oil spills being arranged, discard in rivers and ocean basin, considerable in addition Chemicals belong to oil phase, in case enter the waters, will cause great threat to environment.Administer the waters petroleum pollution and become the task of top priority.Removing oil pollution of waters dyes and is unusual difficulty.The improvement of petroleum pollution has chemical process and physical method in the world at present.
Chemical process:, adopt emulsification dispersion, oil-collecting or coagulate oily method improvement by pollution condition.To the oil film of thickness less than 1 millimeter, it is effective adopting the oil pollution of chemical oil spill dispersant cleaning water body.Yet the medicine that chemical debridement methods consumption is a large amount of also may produce secondary pollution.
Physical method: comprise the oil fence, contamination removing ship and attached retrieving arrangement and oil absorption material.These methods are with the variation of sea situation and meteorological conditions, and it is bigger to reclaim capacity variation, when working conditions is abominable, because the upheaval of the motion of ocean current, wave rises and falls, make the greasy dirt of water surface be easy to drift with the tide, and enlarge contaminated area.
Utilizing magnetic liquid to remove the sea greasy dirt is a kind of novel surface and oil contaminant recycling and control method: spray magnetic liquid at water pollution oil meter face, under the action of a magnetic field, greasy dirt produces orientation and moves, reclaims.
Summary of the invention
The invention provides a kind of adsorbing oil dirt on water control of Sustainable development requirement, suspending type magnetic particle of administering and preparation method thereof of meeting, the magnetic particle spreading that makes is in the greasy dirt surface, can form suspending type magnetic particle one greasy dirt mixed system with greasy dirt, under the action of a magnetic field, thereby magnetic particle one fluid mixed system reaches oil pollution of waters control, administers purpose to the field direction motion.
The present invention is achieved through the following technical solutions: adopt industrial residue coal fly ash hollow micro bead (to call cenosphere in the following text) as carrier, the parcel ferrite layer makes suspending type magnetic particle on the cenosphere surface.The chemical constitution of cenosphere is mainly SiO
2, Al
2O
3, cenosphere and ferrite mass ratio are 1: 1～1: 5.
Described ferrite is meant spinel type ferrite and hexaplanar magneto-plumbite type ferrite (ferrite that nickel, cobalt, manganese, barium, strontium, zinc and above each elements compounding are mixed and obtained).
Adopt chemical process or physical method to make suspending type magnetic particle at cenosphere surface parcel ferrite layer.Chemical process is meant: any method in coprecipitation method, hydrothermal synthesis method, microemulsion method, metal alkoxide sol-gel method, polymer-network gel method, citrate sol-gel method, organic coordination compound precursor process, self propagating high temperature synthesis method, the sintering process.Physical method is meant: adhesion process, mix any method of technology.
Suspending type magnetic particle and tensio-active agent stir the back spreading in the greasy dirt surface, can form suspending type magnetic particle-greasy dirt mixed system with greasy dirt.Under the action of a magnetic field, the magnetic particle of formation-fluid mixed system produces controlled motion.
The suspending type magnetic particle that makes as shown in Figure 1.1 is the ferrite integument in the diagram; 2 is cenosphere.
Effect of the present invention: the magnetic particle that makes is suspended in the fluid surface, even after water body inside is sunk in stirring, still can float the maintenance suspended state.With suspending type magnetic particle spreading oil pollution of waters surface, magnetic particle adsorbs greasy dirt and forms the magnetic mixed system with greasy dirt.Under the action of a magnetic field, thereby the magnetic particle of formation-fluid mixed system reaches oil pollution of waters control, administers purpose to the field direction motion.
The chemical constitution of cenosphere is mainly SiO
2, Al
2O
3,, can not cause secondary pollution to environment for one of earth's crust mineral composition material.After suspending type magnetic particle was adsorbed, collects simultaneously, through oil removal treatment, the basic no change of its magnetic properties still can be reused.The oil pollution of adopting the suspension type magnetic adsorptive material to administer water surrounding meets Sustainable development requirements such as the ecological economy, recycling economy.
