Comparison of Effect of Water Grinding,Water Washing and Grinding on Quality of Realgar by Scanning Electron Microscopy-energy Dispersive Spectrometer
Objective: To explain the effect of water grinding
water washing and grinding on the quality of Realgar by comparing the contents of As2S2 and elements in different processed products.At the same time
to identify water grinding products
water washing products and grinding products rapidly. Method: To determine the content of As2S2 in different processed products of Realgar by the method in the 2015 edition of Chinese Pharmacopoeia.Scanning electron microscopy-energy dispersive spectrometer (SEM-EDS) was used to observe the surface morphology of different processed products and determine the contents of elements in different processed products. Result: The content of As2S2 in different processed products ranked as water grinding products > water washing products > grinding products.The surface morphology of water grinding products was similar to the surface morphology of water washing products
but the surface morphology of grinding products was different from theirs.The content of oxygen in different processed products showed the trend of grinding products > water washing products > water grinding products. Conclusion: It can be distinguished between water grinding products and grinding products by SEM-EDS
it provides a certain technical support for the identification of different processed products of Realgar.The effect of water grinding on removing impurities and reducing the toxicity is best
quality of water grinding products is better than the quality of water washing products and grinding products
which shows that water grinding for Realgar has scientific basis.
