Abstract

The invention discloses a kind of methods for quickly identifying seawater and fresh water pearl powder, its technical solution is: with the commercially available pearl powder sample of -60 radiated by gamma-ray of cobalt of doses, irradiated sample discoloration is fresh water pearl powder, and what irradiated sample did not change colour is sea water pearls powder.The beneficial effects of the present invention are: this method identifies, speed is fast, it is easy to operate to identify, it is low-cost to identify.

Description

A kind of method of quick identification seawater and fresh water pearl powder
Technical field
The present invention relates to a kind of methods for identifying seawater and fresh water pearl powder, and in particular to a kind of fast using nuclear radiation technology The method that speed identifies seawater and fresh water pearl powder, belongs to radiation physics technical field.
Background technique
Pearl powder is exactly the good merchantable brand of skin maintenance and cosmetic benefits from ancient times, have calm the nerves arresting convulsion, improving eyesight disappear screen, solution taking poison and growing muscle due, moistening skin and eliminating spot The effect of, the deep favor by people always.Pearl powder is divided into sea water pearls powder and fresh water pearl powder, and currently on the market, seawater is precious Pearl powder is made by the nacre of the pteria martensii shell of seawater, and fresh water pearl powder is made by fresh water pipless pearl.Seawater and light Water pearl powder is all white or canescence, it is difficult to the naked eye be distinguished.Because the raw material and seawater, the fresh water that produce pearl powder are precious The price of the difference of pearl powder function, seawater and fresh water pearl powder has larger difference, and general sea water pearls powder is compared with fresh water pearl powder valence The expensive 2 times or more of lattice.But market pearl powder product is more chaotic, and most of product does not indicate that the raw material of pearl powder is sea water pearls shell Or fresh water pipless pearl, not necessarily true being labelled with, the serious infringement interests and rights of consumer.
Patent No. ZL200610155553.X national inventing patent and paper " pearl radiation coloring (not this letter one, Huang Rongmin) ", " Pear Dyeing Techniques By Irradiation research (Zou Weimin) ", " Radiation-induced Colouring of pearl studies (Sha Renli) " report Change the technology of fresh water pearl color using irradiation, which is that can convert tetravalence for bivalent manganese using high-energy ray Manganese and the principle that color is presented change, deepen pearl color.In fresh water pearl divalent manganese content it is higher (mass fraction be greater than 100 ×10-6), the radiation treatment through doses, wherein bivalent manganese is converted into tetravalent manganese, and color is substantially change, and seawater is precious Extremely low (mass fraction is less than 100 × 10 for manganese element content in pearl layer-6), it is also difficult to reach the effect obviously changed colour even across irradiation Fruit.
Fresh water pearl can be changed colour and the sea water pearls that cannot change colour using radiation treatment, can also equally make fresh water pearl powder Change colour and sea water pearls powder cannot be made to change colour, but up to the present, there are no using irradiancebased method technology for identify seawater and The report of fresh water pearl powder.
Summary of the invention
The purpose of the present invention is to provide a kind of the identification seawater and fresh water pearl powder simple and quick using irradiation technique Method is used for operating unit and the selection of market surpervision department.
In order to reach the purpose of the present invention, the technical solution adopted by the present invention is that:
With the sample of the commercially available pearl powder of -60 radiated by gamma-ray of cobalt of doses, irradiated sample discoloration is fresh water Pearl powder, what irradiated sample did not change colour is sea water pearls powder.
The irradiation dose of -60 gamma ray of cobalt must be greater than 10kGy.Irradiation dose pearl powder discoloration less than 10kGy is unknown It is aobvious, identification effect is not achieved;When greater than 10kGy irradiation dose, the bigger discoloration of irradiation dose is more obvious.
The irradiation dose of above-mentioned -60 gamma ray of cobalt is 10kGy~13kGy.
The irradiation time of above-mentioned -60 gamma ray of cobalt is irradiation 6~12 hours.
Can observe its color change more clearly as degree, usual 0.5g or so can meet to be wanted the sample size of pearl powder It asks.
The beneficial effects of the present invention are: 1. identifying quickly, accurate identification result can be obtained in 12 hours;2. method is simple Single, sample is not required to special pre-treatment, and irradiation technique process is simple;3. low-cost, 200 yuan of left sides of per kilogram irradiated material charge The right side identifies only 10 yuan or so of expense of each sample;4. irradiation technique is mature and there are irradiation processing in popularization and application, all parts of the country Mechanism is available.
Detailed description of the invention
Fig. 1 is the fresh water pearl powder before and after radiation treatment;
Fig. 2 is the sea water pearls powder before and after radiation treatment.
1. predose is in canescence;2. being in grey black after irradiation;3. predose is in canescence;4. after irradiation, in greyish white Color.
