In LIBS analysis, the target is irradiated with a high-powered laser beam, resulting in melting and evaporation of a part of the irradiated material and converts it into a micro-plasma plume. Atoms and ions in the plasma plume form the excited states, and on cooling of the plasma, these...
In the samples from the superimposed area, the average concentration of 7 PTEs showed a trend of Zn (279.56) > Cr (158.73) > Cu (145.95) > Pb (145.77) > As (19.78) > Cd (4.44) > Hg (0.22). Compared to the standard GB15618–2018, Cd, Cu, Pb, and Zn exceed the amounts, ...
