Abstract
|
|
|
|
Scanning electron microscope/energy-dispersive X-ray spectroscopy (SEM/EDX) is a rapid, non-destructive, and multi-elemental analytical technique used for the elemental analysis and chemical characterization of the selected surface of the sample. In this study, the elemental concentration ratios of four cicada's exuviae including Cicadidae Periostracum [Cryptotympana atrata (Fabricius, 1775), Hyalessa maculaticollis (Motschulsky, 1866), Meimuna opalifera (Walker, 1850), and Platypleura kaempferi (Fabricius, 1794)] were analyzed using SEM/EDX for the first time. C, O, Cl, and K were found in all studied species. However, S and Mg were only found in H. maculaticollis and P. kaempferi, respectively. The results imply that this SEM/EDX technique could be used and applied as a crucial potential tool, analyze both microstructure and element, and manage the quality of the distributed medicinal medicines.
