Description
Technical field
The assay method and the device that the present invention relates to the method that is collected in the yellow sand particle that swims in the atmosphere and device thereof and the yellow sand particle that utilizes this method to collect is carried out.
Technical background
The sand in desert, ground is blown afloat by high wind in the China's Mainland, to travel far across the ocean by overhead north wind band to the west and comes Japan as yellow sand.The diameter of yellow sand particle is different along with the difference of region.It is said that produce near China's Mainland, ground at the distance yellow sand, the diameter of yellow sand particle is 20～30 μ m.And producing ground Japan far away at the distance yellow sand, the diameter of yellow sand particle is 4～5 μ m.
In order to investigate the yellow sand coating of particles in the atmosphere, or differentiate the chemical substance that wherein contains, utilize filtrator to collect yellow sand particle in the atmosphere, and utilize microscopic examination, or carry out chemical analysis.
In addition, as the device of measuring the yellow sand particle size distribution, what prior art adopted is the device practicability based on multistage collision (カ ス ケ-De イ ソ パ Network ) mode.Should be to utilize based on the determinator of multistage collision mode by changing its flow direction separates particle from fluid collision method rapidly behind the fluid collision collecting board.The impinger that the particle diameter that makes 50% collection efficiency is changed in proper order is concatenated into multistage, and the particle diameter of 50% collection efficiency at different levels according to the measurement result of collecting amount in each grade, is obtained the distribution of the granularity in the fluid as the representative diameter of each grade.
But, the yellow sand particle that utilizes microscopic examination in atmosphere, to swim, or utilize the collection method of the filtrator that various chemical analysis instruments must be provided, and particularly waft to the yellow sand particle of Japan because tiny degree to 4～5 μ m, it is extremely difficult extracting each particle separately.In addition, because when utilizing microscopic examination, observe yellow sand particle attached to the state on the filtrator, so because of the influence of the filtrator picture of background, and make the picture of particle not distinct.Consequently there is the problem that is difficult to observe the yellow sand particle.Also having, even the yellow sand particle of collecting is offered various analytical instrument, is difficult owing to extract the yellow sand particle separately from filtrator, so be necessary to utilize instrument to analyze with the state attached to filtrator.Under this occasion, have following problem, in fluorescent x-ray analyzer etc., be difficult only for example to particle irradiation X ray, substantial analysis is impossible, or is difficult to carry out processing in early stage etc.
In addition, utilization is based on the existing determinator of existing multistage impinger mode, under the situation of the size-grade distribution of measuring the yellow sand particle, on its principle, because the resolution (resolution) of particle diameter is by the quantity decision of collecting board, so do not expect to utilize polymolecularity to measure size-grade distribution.
Summary of the invention

To achieve the above object, the collection method of yellow sand particle of the present invention is to collect the method that is contained in the yellow sand particle in the atmosphere, it is characterized in that, when utilizing pump to be drawn into atmosphere in the container, the sparking electrode that utilization is provided with in described container produces the one pole ion, make the particle that swims of the yellow sand particle that is contained in the atmosphere charged, in described container, described charged particle is collected in described relatively sparking electrode and applies on the collecting electrode of potential difference (PD).
In the method for collection yellow sand particle of the present invention, in being provided with the container of sparking electrode and collecting electrode, inside sucks atmosphere, owing to utilize the one pole ion that produces from sparking electrode to make on the charged surface that is collected in collecting electrode of yellow sand particle the atmosphere, so can extract the yellow sand particle of collection easily separately, can easily offer various analytical instrument, utilize microscopic examination also easy.
On the other hand, the assay method of yellow sand particle of the present invention is characterised in that: under the state of the disperse state of keeping the particle that the method for utilizing above-mentioned collection yellow sand particle collects, measure the spatial intensity distribution of the diffraction scattering light that irradiating laser obtains, only obtain size-grade distribution and granule density in the particle diameter scope that contains the yellow sand particle according to the result of its mensuration.
In the assay method of yellow sand particle of the present invention, to the yellow sand particle of on above-mentioned collecting electrode, collecting, try to achieve size-grade distribution by the particle size distribution method of utilizing the laser diffraction and scattering formula, can on the basis of polymolecularity, measure the size-grade distribution and the granule density of yellow sand particle.
Promptly, in the particle size distribution method of laser diffraction and scattering formula, generally, to the determined particle swarm irradiating laser of disperse state, measure the spatial intensity distribution of resulting diffraction scattering light, utilizing this intensity distributions is criterion with the scattering theory of rice (ミ-) or the diffraction theory of fraunhofer, according to the measurement result of the spatial intensity distribution of diffraction scattering light, by calculating, obtain the size-grade distribution of determined particle swarm based on the scattering theory of rice and the diffraction theory of fraunhofer.If utilize the particle size distribution of this laser diffraction and scattering formula, then by the concentration of the medium that are used for making determined particle swarm to disperse in proper range, then can enough polymolecularities obtain size-grade distribution in wide particle diameter scope.
But, even to the yellow sand particle direct irradiation laser in the atmosphere measuring diffraction scattering light because the low excessively relation of concentration of yellow sand particle in the atmosphere, can not obtain being used to obtain the sufficient diffraction scattering light of size-grade distribution.
Therefore, in the present invention, atmosphere is drawn in the container, make the particle that contains the yellow sand particle in container charged, and be collected on the passive electrode, the particle that disperses this collection on the basis of the concentration range that makes the particle size distribution that is fit to the laser diffraction and scattering formula, irradiating laser is to measure the spatial intensity distribution of diffraction scattering light.Therefore, can in the wide particle diameter scope identical, on the basis of polymolecularity, measure the size-grade distribution of the particle that exists in the atmosphere that is attracted in the container with the particle size distribution of common laser diffraction and scattering formula.Then, particle diameter scope at the yellow sand particle of measuring point, owing to judge by investigation etc. in advance, so as long as size-grade distribution of its particle diameter scope of mensuration, the yellow sand particle that its particle that constitutes size-grade distribution becomes to take as the leading factor, so its measurement result just can roughly correctly be represented the size-grade distribution of the yellow sand particle that swims in the atmosphere.
In addition, in its particle size distribution, by particle size distribution device to employed laser diffraction and scattering formula, utilize the known particle of concentration to demarcate in advance, separate easily from the flow of pump and the time of its driving owing to be attracted to the amount of the atmosphere in the container, so can obtain the concentration of yellow sand particle in the atmosphere.
