Embodiment 1

[0021] 1 Instruments and samples

[0022] Thermo Scientific Niton XL3t XRF Analyzer Portable X-ray Fluorescent Elemental Analyzer; cinnabar genuine products and cinnabar counterfeit products are collected in daily inspections, and are tested and confirmed according to the 2015 edition of "Chinese Pharmacopoeia" under a cinnabar variety; Zixue powder, Samples of Baoying Powder, Bingboran Powder, and Tianwang Buxin Pills were purchased from the market.

[0023] 2 Methods and results

[0024] 2.1 Method

[0025] Take an appropriate amount of sample powder, place it in the sample stage, and select the copper-zinc ore module that comes with the instrument to scan.

[0026] 2.2 Results

[0027] The XRF identification result of true and false cinnabar is consistent with the laboratory results, the results are shown in Figure 1-6 .

[0028] 3 Discussion

[0029] Comparing the spectra, it can be seen that the counterfeit cinnabar has no corresponding peaks in the Hg characterist...

Abstract

The invention discloses a method for distinguishing true and false cinnabar by means of x-ray fluorescence spectrometry analysis. A new method is established for the identification of the cinnabar and Chinese patent medicines containing the cinnabar; the method has the characteristics of being simple, rapid, visual and reliable. The method belongs to the field of chemical detection. The method adopts an X-ray fluorescent element analyzer to analyze and distinguish the authenticity of the cinnabar in a sample. The method can be used for analyzing and distinguishing the authenticity of the cinnabar in traditional Chinese medicines such as Zixue san, Baoying powder, Bingpeng San and Tianwang Buxin pills.

Description

technical field [0001] The invention belongs to the field of chemical detection, in particular to a method for identifying true and false cinnabar by X-ray fluorescence analysis. Background technique [0002] The X-ray fluorescence spectroscopic analysis method has the advantages of a wide range of analyzed elements, less interference, short analysis time, and non-destructive samples. Therefore, elemental analysis has unique advantages. Identification technology has been developed rapidly. [0003] Cinnabar, also known as cinnabar, is a sulfide mineral, mainly containing mercury sulfide (HgS). After excavation, select the pure one, use a magnet to absorb iron-containing impurities, and then wash away miscellaneous stones and sediment with water. The color is bright red or dark red, shiny, slightly smelly and light in taste. It has the effects of clearing heart, calming convulsions and calming nerves, and has certain toxicity. According to the author's investigation, the q...
