は好ましくないという問題点があった。(Problems to be Solved by the Invention) However, since it is difficult to completely recover the oil floating or dispersed on the water surface by these methods, some oil remains in the water without being recovered. There was a problem. Further, the method of suspending or dispersing oil in water using an oil treating agent does not collect oil as a pollution source, and thus is not preferable from the viewpoint of preventing environmental pollution.
（問題点を解決するための手段） 本発明者等は、前記の問題点を解決してオイルを効率よ

の回収方法を提供するものである。That is, the present invention, a magnetic polymer powder in which a magnetic substance is supported on a polymer comprising a vinylpyridinium quaternary salt homopolymer or a copolymer containing a vinylpyridinium quaternary salt is sprayed on an oily substance on the water surface. Then, an oil recovery method is provided, in which the magnetic material-supported polymer is allowed to capture the oil and then the oil is recovered by suction using a magnet.

好ましい。Here, a copolymer containing a vinylpyridinium quaternary salt homopolymer or a vinylpyridinium quaternary salt used as the polymer easily dissolves in water because it has water solubility, and has an affinity with oil. It is also excellent in the ability to carry a magnetic material, and is most suitable for the oil recovery method of the present invention. As the copolymer containing the vinylpyridinium quaternary salt, a copolymer of a vinylpyridinium quaternary salt and an acrylamide derivative, a styrene derivative, a vinyl ether derivative or the like is preferable. As the polymer,
Although it is possible to use polyvinyl alcohol, polyacrylamide, polyacrylic acid salt, etc., considering the water solubility, it is preferable to use a vinylpyridinium quaternary salt homopolymer or a copolymer containing a vinylpyridinium quaternary salt. preferable.

Fine particles of 2000 liter or less such as magnetite, cobalt ferrite, nickel ferrite and barium ferrite are preferable, and fine particles having an average particle diameter of 1000 liter or less are particularly preferable in terms of dispersibility in the polymer.

た後、通常の方法で乾燥すればよい。As a method of dispersing the magnetic substance in the polymer as described above, an average particle size of 2000 is preferable in an aqueous solution of the polymer.
Å The following magnetic substances may be added and sufficiently dispersed by ultrasonic waves, and then dried by a usual method.

回収効果が小さくなるので好ましくない。As a mixing ratio of the magnetic substance supported on the polymer, a composition of 0.1 to 1.5 parts by weight is suitable for 1 part by weight of the polymer. When the composition of the magnetic material is 1.5 parts by weight or more, the affinity of the magnetic polymer with the oil decreases, and when it is 0.1 parts by weight or less, the magnetism of the polymer deteriorates and the effect of collecting oil by the magnet decreases, which is not preferable. .

とにより、オイルを効率よく回収することができる。When the polymer obtained by carrying out the above and supporting the magnetic substance is pulverized into a powder and sprayed on the surface of the water in which the oil is suspended, the oil becomes substantially magnetic due to the adhesion of the powder. Therefore, the oil can be efficiently collected by using a magnet for suction.

When a samarium-cobalt magnet of Mega Oersted was used to sweep the surface of the water, the oil film on the surface of the water was attracted onto the Saran wrap film. No heavy oil was floating on the water surface after removing the magnet, and the magnet was not contaminated when the Saran wrap film was removed.
