Quantitative analysis of Pb in soil samples by laser-induced breakdown spectroscopy with a simplified standard addition method

In this work, different soil samples were extracted from seven sites in the vicinity of the Northwest China Lead–Zinc Smelter. A simplified standard addition method with LIBS (SAM-LIBS) was proposed to carry out quantitative analysis of Pb in solid soil samples. The method proposed in this work can be used for rapid assessment of the contaminants in soils.
