Quantitative analysis of metals in waste foundry sands by calibration free-laser induced breakdown spectroscopy
Laser-induced breakdown spectroscopy (LIBS) was applied for quantitative analysis of the elemental composition of waste molding and core sands produced from industry as part of the casting process. To perform the analysis, waste foundry sands (WFS) were collected from metalcasting foundries and prep...

To perform the analysis, waste foundry sands (WFS) were collected from metalcasting foundries and prepared in the form of solid pellets with the addition of polyvinyl alcohol as binder.
