Abstract
Discerned the false from the genuine the invention discloses a kind of x-ray fluorescence analysis the method for calamine, be calamine and can be made into the discriminatings of other Chinese medicines of powder and establish new method, without complicated cumbersome operation, with it is simple and direct, quick, directly perceived, reliable the characteristics of.Belong to field of chemical detection.This method carries out analysis detection using XRF elemental analyser to calamine.The present invention differentiates available for the true and false of calamine or other Chinese medicines.
Description
Technical field
The invention belongs to field of chemical detection, especially a kind of x-ray fluorescence analysis is discerned the false from the genuine the method for calamine.
Background technology
The elemental range wide (can be determined from Mg to Fm) of X-ray fluorescence spectra analysis method tool analysis, interfere less,
Sample need not be separated, analysis method comparison simplicity, analytical concentration wider range (can all be analyzed from constant to micro), have sensitivity
High, sample treatment is simple, detection is quick, the advantage of uniqueness is embodied in good selective, therefore elementary analysis, with just
The marketization of Formula X ray fluorescence spectrometer is taken, the identification technology of X-ray fluorescence spectra has obtained rapid development.
Calamine is carbonate mineral calcite race smithsonite, the main (ZnCO containing zinc carbonate3), after excavation, clean, shine
It is dry, except impurity elimination stone.Calamine clinic is mainly for external application, and is used as medicine with its processed product.At present, the assay method of calamine is mainly second
The acetic acid disodium titration of diamines four, the detection means sample treatment complexity is cumbersome, it is impossible to the need for meeting field quick detection, because
A kind of quick effective, easy accurately authentication method of this research has certain meaning.
The content of the invention
For above-mentioned deficiency, a kind of method of calamine the present invention is intended to provide x-ray fluorescence analysis is discerned the false from the genuine, is stove
Sweet stone and it can be made into the discriminating of other Chinese medicines of powder and establish new method, without complicated cumbersome operation, with simple and direct, fast
Fast, directly perceived, reliable the characteristics of.
In order to realize above-mentioned technique effect, the technical scheme that the present invention is provided is such：A kind of x-ray fluorescence analysis mirror
The method of other true and false calamine, analysis detection is carried out using XRF elemental analyser to calamine.
Preferably, described XRF elemental analyser refers to Thermo Scientific Niton XL3t XRF
Analyzer portable X-Ray Fluorescence elemental analysers.
Preferably, described analysis detecting step is specially：Sample powder is taken, is placed in XRF elemental analyser,
Selected copper zinc ore module is scanned.
The present invention is compared with conventional method, and tool has the advantage that：
The present invention carries out discriminatory analysis result to calamine using Xray fluorescence spectrometer and shows that calamine is in La1
(9.989), Lb1 (11.823) and Lr1 (11.82) place occur in that the stronger peak of characteristic, are the principle active component of calamine
The Zn-ef ficiency characteristic peak of zinc carbonate, has reflected the architectural feature of calamine well.
Brief description of the drawings
Fig. 1 is the essential element feature spectrogram of certified products calamine；
Fig. 2 is the essential element feature spectrogram of adulterant calamine.
Embodiment
With reference to embodiment, the claim to the present invention is described in further detail, but is not constituted pair
Any limitation of the present invention, any limited number of time modification made in the claims of the present invention, still in the present invention
Claims in.
Embodiment 1
1 instrument and sample
Thermo Scientific Niton XL3t XRF Analyzer portable X-Ray Fluorescence elemental analysers.
Testing conditions：Take sample powder appropriate, be placed in sample stage, selected copper zinc ore module is scanned.
Calamine (identifies) that adulterant calamine is flat through Wuzhou food and medicine inspection institute mesothecium Huang Heng deputy director pharmacist of traditional Chinese medicine
When routine check collect, calamine lotion sample bought by market.
2 results are with discussing
Essential element characteristic spectrum is gone out according to the true and false sample element data that XRF methods are determined, Fig. 1, Fig. 2 is seen.
Compare Fig. 1, Fig. 2 it can be seen that adulterant calamine in Zn characteristic spectrums Ka1 (8.639), Kb1 (9.572) without respective peaks,
Significant difference, need to will only be authenticated sample elemental characteristic spectrum and be analyzed with it, you can obtain quick, directly perceived, effective
The true and false differentiates.
If sample is authenticated in Zn characteristic spectrums Ka1 (8.639), Kb1 (9.572) without characteristic peak, for adulterant.It can be seen that
The method selected herein differentiates that the calamine true and false is practicable.
3 conclusions
The element species and content of sample are authenticated using x-ray fluorescence spectrum method for measuring herein and elemental characteristic spectrum is made
Comparative analysis, can quick discriminating calamine the true and false, compared with methods of other discriminating calamines, with need not enter to sample
Row pretreatment, greatly save analysis time, it is simple and direct quick, accurate objective the advantages of, overcome other method easily by subjective factor
Influence or it is excessively complicated the shortcomings of, it is possible to use the method carries out live primary dcreening operation, improves examination at random targeting rate, can meet daily prison
Rapid screening requirement during pipe.
The foregoing is only presently preferred embodiments of the present invention, it is all done in the range of the spirit and principles in the present invention it is any
Modifications, equivalent substitutions and improvements etc., should be included within the scope of the present invention.
