Abstract

The widely applied copper metal is mainly produced by smelting copper ore, in which fluorine (F) is one of the harmful elements. Therefore, the F content has become a mandatory test index for copper ore. The low excitation efficiency, complex and serious spectral interference makes it difficult to detect F element in copper ore using atomic emission spectroscopy of laser-induced breakdown spectroscopy (LIBS). To address this issue, SrF molecular emission bands were investigated to improve the analytical capabilities of LIBS for the determination of trace F in copper ore. The results demonstrated that the SrF molecular emission band produces a significantly accurate calibration model (R² = 0.9933), with high detection sensitivity (5 ppm), high analytical accuracy (RMSECV = 0.0049 wt%), and high analytical precision (6.64 wt%) for detection of F in copper ore. SrF molecular emission bands in LIBS show great potential for F determination in the copper ore industry. Furthermore, the mechanism behind the emission spectrum for the SrF molecule was also discussed.
