The invention provides the novel preparation method of the magnetic grapefruit peel oil absorption material.

Description

The preparation method of magnetic pomelo peel oil absorption material
Technical field
The present invention relates to a kind of preparation method of magnetic pomelo peel oil absorption material.
Background technology
The leakage of various oils in use, transportation, serious environment pollution, especially huge to the negative effect of the water body such as ocean, river, some oils is as crude oil, lubricating oil biodegradable poor ability in natural environment, holdup time is long, heavy damage ecological environment and the ecological balance.
At present, the method processing all kinds of oil pollution accident of water body the most frequently used is oil absorption material.Common oil absorption material has two large classes, and a class is the oil absorption material of chemical synthesis, and as polypropylene or polyurethane, they have good hydrophobicity and lipophile, but its pole difficult for biological degradation, and expensive.Another kind of is natural oil absorption material, and natural inorganic oil absorption material, as vermiculite, diatomite, because its oil absorbency is low, also absorbs water while oil suction, seldom uses; Natural organic oil absorption material, as porous materials such as raw cotton, agricultural crop straw, lumber fibres, oil absorbency is better, if but without modification, also absorbed water while oil suction.At present, the study hotspot of oil absorption material is the modification of natural organic oil absorption material.
The oil absorption material generally applied now mostly is Powdered, graininess, collects difficulty, easily causes secondary pollution, make it apply to be extremely restricted, for this problem, giving magnetic by natural organic oil absorption material, is a kind of method of simple possible by externally-applied magnetic field separation and recovery.CN102424570A discloses a kind of NiFe 2o 4the preparation method of magnetic material.CN1657663A discloses a kind of multifunction bio-magnet fibre, and this fiber has the complex function of magnetic function, adsorption function, anion and far-infrared functional simultaneously.CN101117218A discloses a kind of preparation method of magnetic porous charcoal, and this invention has that preparation method is simple, absorption property is good, magnetic property is comparatively strong and the advantage of easily regulation and control.CN102895950A discloses a kind of method of Magnaglo active carbon and milipore filter associating oil removing.CN101497028A discloses a kind of method utilizing coal raw materials, magnetic additive, binding agent and surfactant to prepare magnetic active carbon, and this magnetic active carbon has that specific area is high, absorption property good and be easy to the advantages such as recovery.CN1500736A discloses a kind of with MnFe 2o 4or CuFe 2o 4the method of magnetic active carbon is prepared with the compound of active carbon.But the magnetic charcoal introduced in patent is at present all hydrophilic, is used as oil absorption material and removes the less of water body oil spilling.
Summary of the invention
The object of this invention is to provide a kind of preparation method of magnetic pomelo peel oil absorption material.
For achieving the above object, the present invention adopts following technical scheme:
A preparation method for magnetic pomelo peel oil absorption material, is characterized in that the concrete steps of the method are:
A., after pomelo peel is air-dry, clean, constant weight is dried to; Remove yellow appearance skin again, pulverize the pomelo peel particle making 0.25 ~ 1.00mm;
B. ferric trichloride is joined in ethylene glycol and be mixed with the solution that concentration is 1%, then add Ammoniom-Acetate, step a gained pomelo peel particle and oleic acid successively, stir 30min, obtain suspension; This suspension is transferred in band teflon-lined 50mL stainless steel autoclave, is warmed up to 100 DEG C through 30min from 20 DEG C, constant temperature 30min at 100 DEG C, then is warming up to 200 DEG C and constant temperature 6h through 40min, naturally cool to room temperature; The mass ratio of described ferric trichloride, Ammoniom-Acetate, pomelo peel and oleic acid is 2: 17: 1: 2;
C. step b gained pomelo peel is rinsed with deionized water, absolute ethyl alcohol successively, dry, namely obtain magnetic pomelo peel oil absorption material.
The present invention utilizes discarded pomelo peel as raw material, prepare the oil absorption material of hydrophobic oleophilic oil, thus provide the preparation method of the novel magnetic oil absorption material that a kind of convenience is collected, oil absorbency is good, the method is not only simple to operate, and reaction condition is gentle, and raw material used is pomelo peel, its wide material sources, integrated cost is low, and oil absorbency is good, and it is rapidly convenient to collect; Pomelo peel is biodegradable, the requirement of combinational environment friendly materials.
Accompanying drawing explanation
Fig. 1 is that the magnetic pomelo peel oil absorption material that obtains of the embodiment of the present invention is to the curve of adsorption kinetics of diesel oil.As can be seen from Figure 1, magnetic pomelo peel oil absorption material is 27.98 g/g to the adsorption capacity of diesel oil.
Fig. 2 is the room temperature hysteresis curve of the magnetic pomelo peel oil absorption material that the embodiment of the present invention obtains.As can be seen from Figure 2, the saturation magnetization of magnetic pomelo peel oil absorption material is 8.0595emu/g, and coercivity is 73.3G, and remanent magnetism is 0.73934emu/g.
Detailed description of the invention
embodiment one:
(1), after pomelo peel is air-dry, clean, constant weight is dried to; Remove yellow appearance skin again, pulverize the pomelo peel particle making 0.25 ~ 1.00mm;
(2) 0.4g ferric trichloride is joined in 33g ethylene glycol be mixed with the solution that concentration is about 1%, then add 3.4g Ammoniom-Acetate, step a gained pomelo peel particle 0.2g and 0.4g oleic acid successively, stir 30min, obtain suspension; This suspension is transferred in band teflon-lined 50mL stainless steel autoclave, is warmed up to 100 DEG C through 30min from 20 DEG C, constant temperature 30min at 100 DEG C, then is warming up to 200 DEG C and constant temperature 6h through 40min, naturally cool to room temperature; The mass ratio of described ferric trichloride, Ammoniom-Acetate, pomelo peel and oleic acid is 2: 17: 1: 2;
