Preferred embodiment.
Fig. 1 is to show the light salt working year evaluation method according to the present invention based on K-40 measurement of concetration, by 1Kg state
After production light salt is put into sharp beaker in novel Mali and is installed to high-purity gamma spectrometer, analyzes 5000 seconds to 30,000 second, select
Selecting the K-40 peak value in Isosorbide-5-Nitrae 60KeV energy band has the time point (10,000 seconds) of appropriate peak value form and obtains radiant numerical value
Chart.
Firstly, the technology for summarizing the invention for solving problem of the prior art is former before illustrating technology of the invention
Reason.Light salt production stage can be summarized as making the step of evaporation of seawater is to obtain salt crystallization using sunlight.Seawater Quality Safety rule
The cleaning of water quality benchmark, insoluble component and the sandy soil and ferrocyanide ion etc. such as hydrogen ion concentration, Escherichia coli sum is proposed in fixed
Whether property, the heavy metal pollutions benchmark such as arsenic, lead, cadmium, mercury.
In addition, since 2013, it, can with the stickup on sack for the transparency for ensuring domestic light salt currency structure
The method of the label in confirmation place of production area, the producer and working year carries out the management of tracing to the source of domestic light salt, there is problems in that
The method of light salt working year is not able to confirm that in circulating step.
Therefore, as previously mentioned, currently invention addresses the method for not being able to confirm that light salt working year in circulating step,
The constituent of salt is lost the characteristic of a part by brine to distinguish working year in the quasi- production keeping step using salt.
The present invention is surveyed using high-purity radionuclide analyzer (High Purity Germanium Spectrometer)
The concentration for determining the natural radionuclide i.e. kalium-40 (K-40) that light salt must include is estimated by the concentration of the K-40 of measurement
The working year of the light salt.
In other words, of the invention to estimate the method for light salt working year with salt pan or city by measurement K-40 concentration
The light salt that circulates on field or to dissolve brine out from the light salt be object, passes through radionuclide analysis-e/or determining radioactivity
After nucleic element, that is, K-40 concentration, the working year of the light salt is estimated by the K-40 concentration of measurement.
In addition, the working year in order to estimate light salt as the aforementioned, acquires each actual production year in multiple salt pans
Light salt as sample sample and after measuring the radioactive nucleus prime element i.e. concentration of K-40, relevant table is obtained, to make
Surely the management standard of tracing to the source of working year can be distinguished.
As previously mentioned, the light salt that is circulated in the market by management standard stochastic buying of tracing to the source and with light salt or from the day
It is after object measures the radioactive nucleus prime element i.e. concentration of K-40, by the K-40 concentrations control of measurement that day salt, which dissolves brine out,
Management standard table is traced to the source to estimate the light salt or dissolve the working year of brine out from the light salt.
In addition, as the aforementioned according to the working year for management standard estimation light salt of tracing to the source when, when passing through radionuclide
When kalium-40 (K-40) concentration of analysis-e/or determining belongs in the range of 130~220Bq/kg, the working year of the light salt is estimated
Calculate is 1~2 year;When the kalium-40 concentration of measurement belongs to 130Bq/kg or less, the working year of the light salt is estimated as 3 years
More than.
Also, it has been observed that the concentration for the natural radionuclide i.e. kalium-40 (K-40) that must include as measurement light salt
Radionuclide analyzer, the present invention in use HpGe gamma ray nucleic detector (HPGe Gamma
Spectroscopy, the production of U.S. Canberra company, relative efficiency: 30%, corresponding energy band: Isosorbide-5-Nitrae 60KeV) it is measured.
In general, the salt concentration of seawater is 35%, by sodium chloride (27g/kg), magnesium chloride (3.8g/kg), magnesium sulfate
(1.7g/kg), calcium sulfate (1.3g/kg), potassium sulfate (0.9g/kg), calcium carbonate (0.1g/kg), magnesium bromide (0.1g/kg) structure
At the relative ratios between salt are unrelated with salinity, are fixed in any one of world sea area.
In addition, with fixed ratio, there are alkali metal (hydrogen, lithium, sodium, potassium, rubidium, caesium, franciums) always in seawater.Salt Tanaka's moisture
Fallen in rear remaining light salt crystal by solar evaporation, and there are these elements with fixed ratio, when standing for a long time, this
A little constitution elements can be lost with fixed ratio.
As previously mentioned, passing through natural radioactivity nucleic remaining in radionuclide analysis-e/or determining light salt in the present invention
That is the K-40 concentrations control of measurement is traced to the source management standard to estimate the working year of light salt by the concentration of K-40.Here, radiation
Property Radionuclide analysis instrument be sense radiant gamma energy and by sensing gamma energy waveform analysis detection
Radioactive nucleic is to measure the device of radionuclide intensity.
The radioactive decay of radiopotassium (Potassium-40, half-life period: 1,200,000,000 5 thousand ten thousand years)
40K+e-→40Ar+ gamma ray (gamma energy: 1.46MeV)
For technology of the invention, have purchased in the salt pan in the island the Xin Anjunzeng face for representing the domestic light salt place of production for giving birth to
The concentrated seawater for producing salt and each working year annual May are to the salt produced between August.The 1Kg light salt of purchase is put into Mali
Interior benefit beaker, utilizes HpGe gamma ray nucleic detector (HPGe Gamma Spectroscopy, U.S. Canberra company
Production, relative efficiency: 30%, corresponding energy band: Isosorbide-5-Nitrae 60KeV) measurement K-40 10,000 second.The radiant numerical value chart obtained is such as
Fig. 1.
[embodiment]
Select May to the salt water produced between August in the salt pan in the island the Xin Anjunzeng face for representing the domestic light salt place of production and
Light salt, using salt water as comparison other measures the radioactive nucleus prime element i.e. concentration of K-40 in the light salt of each working year and obtains
Relevant table out, and propose to distinguish the management standard of tracing to the source of working year again.
[table 1]
By proposing the management standard of tracing to the source such as aforementioned table 1, even if the light salt to circulate in stochastic buying market, with random
The light salt of purchase dissolves brine out from the light salt for the object measurement radioactive nucleus prime element i.e. concentration of K-40
Estimate the working year of the light salt.
As described above, the amount that technology of the invention detects remaining K-40 by gamma nucleic detector can more be held
Except the working year for estimating light salt of changing places, also it can pass through the pipe of tracing to the source of light salt by the working year of estimation light salt
Reason carrys out management quality.Also, by estimating that the manufacturing period of light salt can ensure the transparency of the process of circulation.
The present invention is not limited to embodiments above-mentioned, can implement a variety of in technical idea allowed band of the invention
Deformation.
