Embodiment
The light salt working year evaluation method based on K-40 measurement of concetrations of the present invention is illustrated referring to the drawings
Preferred embodiment.
Fig. 1 is to show the light salt working year evaluation method based on K-40 measurement of concetrations according to the present invention, by 1Kg states
Production light salt is put into the interior sharp beaker of new Mali and is installed to after high-purity gamma spectrometer, analyzes 5000 seconds to 30,000 second, choosing
Select K-40 peak values can have the time point (10,000 seconds) of appropriate peak value form and draw radiant numerical value in Isosorbide-5-Nitrae 60KeV with
Chart.
First, before the technology of the explanation present invention, the technology original of the invention for solving problem of the prior art is summarized
Reason.Light salt production stage can be summarized as making evaporation of seawater to obtain the step of salt is crystallized using sunlight.Seawater Quality Safety is advised
The water quality benchmark such as hydrogen ion concentration, Escherichia coli sum, the cleaning such as insoluble component and sandy soil and ferrocyanide ion are proposed in fixed
Whether is property, the heavy metal pollution benchmark such as arsenic, lead, cadmium, mercury.
In addition, since 2013, can with the stickup on sack to ensure the transparency of domestic light salt currency structure
Confirm that the method for the label of 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 it was previously stated, currently invention addresses the method that light salt working year is not able to confirm that in circulating step,
The constituent for intending salt in the production keeping step using salt is lost in the characteristic of a part to distinguish working year by bittern.
The present invention is surveyed using high-purity radionuclide analyzer (High Purity Germanium Spectrometer)
Determine the concentration for the natural radionuclide i.e. kalium-40 (K-40) that light salt must be included, estimated by the K-40 of measure concentration
The working year of the light salt.
In other words, the method for the invention that light salt working year is estimated by measuring K-40 concentration is with salt pan or city
The light salt that is circulated on the field or bittern is dissolved from the light salt is object, passes through radionuclide analysis-e/or determining radioactivity
After nucleic element is K-40 concentration, the working year of the light salt is estimated by the K-40 concentration of measure.
In addition, the working year in order to estimate light salt as the aforementioned, each actual production year is gathered in multiple salt pans
Light salt as sample sample and after determining radioactive nucleus prime element i.e. K-40 concentration, the table of correlation is drawn, so as to make
Surely the management standard of tracing to the source of working year can be distinguished.
As it was previously stated, the light salt that is circulated by management standard stochastic buying in the market of tracing to the source and with light salt or from the day
Day salt is dissolved after the bittern that determines radioactive nucleus prime element i.e. K-40 concentration for object, by the K-40 concentrations controls of measure
The working year for tracing to the source management standard table to estimate the light salt or dissolve the bittern from the light salt.
In addition, when estimating the working year of light salt according to management standard of tracing to the source as the aforementioned, 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 as 1~2 year;When the kalium-40 concentration of measure belongs to below 130Bq/kg, the working year of the light salt is estimated as 3 years
More than.
Also, it has been observed that it is used as the concentration for determining the natural radionuclide i.e. kalium-40 (K-40) that light salt must be included
Radionuclide analyzer, the present invention in use HpGe gamma ray nucleic detector (HPGe Gamma
Spectroscopy, U.S. Canberra company makes, relative efficiency:30%, mutually should be able to band:1,460KeV) 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
Into the relative ratios between salt are unrelated with salinity, are all fixed in any one marine site of the world.
In addition, there is alkali metal (hydrogen, lithium, sodium, potassium, rubidium, caesium, francium) all the time with fixed ratio in seawater.Moisture in salt pan
Fallen by solar evaporation in rear remaining light salt crystal, be also there are these elements with fixed ratio, when standing for a long time, this
A little constitution elements can be lost in fixed ratio.
As it was previously stated, passing through natural radioactivity nucleic remaining in radionuclide analysis-e/or determining light salt in the present invention
I.e. K-40 concentration, the K-40 concentrations controls of measure are traced to the source management standard to estimate the working year of light salt.Here, radiation
Property Radionuclide analysis instrument be sense radiant gamma energy and the gamma energy waveform for passing through sensing analysis detection
Radioactive nucleic is to determine the device of radionuclide intensity.
- radiopotassium (Potassium-40, half-life period:1200000000 5 thousand ten thousand years) radioactive decay
40K+e-→40Ar+ gamma ray (gamma energies:1.46MeV)
For the technology of the present invention, it be have purchased in the salt pan in the Xin Anjunzeng islands face for representing the domestic light salt place of production for giving birth to
Produce salt concentrated seawater and each working year annual May to the salt produced between August.The 1Kg light salt of purchase is put into Mali
Interior sharp beaker, utilizes HpGe gamma ray nucleic detector (HPGe Gamma Spectroscopy, U.S. Canberra company
Make, relative efficiency:30%, mutually should be able to band:1,460KeV) determine K-40 10,000 seconds.The radiant numerical value chart drawn is such as
Fig. 1.
[embodiment]
Select May to the salt water produced between August in the salt pan in the Xin Anjunzeng islands face for representing the domestic light salt place of production and
Light salt, the concentration that radioactive nucleus prime element in the light salt of each working year is K-40 is determined by comparison other of salt water and is obtained
Go out the table of correlation, and propose that the management standard of tracing to the source of working year can be distinguished again.
[table 1]
By proposing the management standard of tracing to the source such as foregoing table 1, even if the light salt circulated in stochastic buying market, with random
The bittern that the light salt of purchase or dissolved from the light salt determines radioactive nucleus prime element i.e. K-40 concentration for object, you can
Estimate the working year of the light salt.
As described above, the technology of the present invention is detected remaining K-40 amount by gamma nucleic detector and can more held
Outside the working year of estimation light salt of changing places, also it can pass through the pipe of tracing to the source of light salt by estimating the working year of light salt
Reason carrys out management quality.Also, it is able to ensure that the transparency of the process of circulation by estimating the manufacturing period of light salt.
The present invention is not limited to foregoing embodiment, can implement a variety of in the technological thought allowed band of the present invention
Deformation.
