Quantitative Analysis of Trace Metal Ions in Aqueous Solutions Using Electrodeposition-Assisted Laser-Induced Breakdown Spectroscopy (EA-LIBS)
https://doi.org/10.1007/s11814-024-00291-2
Abstract
Laser-induced breakdown spectroscopy (LIBS) is a powerful elemental analysis technique capable of in-situ and real-time
analysis, depending on its application. Therefore, it has the potential to quantify trace metal ion concentrations for chemical
control in the harsh environments of nuclear power plants. However, to apply this technique, the limitations of conventional
LIBS in liquid analysis must be addressed. In this study, we overcame these limitations using electrodeposition to perform
phase conversion to a solid state and preconcentration. We derived calibration curves and determined the limits of detection
for quantifying nickel (Ni) and iron (Fe) ion concentrations in aqueous solutions. The calibration curves showed high linearity
with R 2 values over 0.9, and the detection limits for both elements were improved to a low ppm range (Ni: 1.273 ppm,
Fe: 1.412 ppm). Furthermore, partial least-squares regression was applied for multi-element analysis to enhance prediction
accuracy, allowing simultaneous detection of Ni and Fe.
