Abstract:
A developing technique, laser ablation and fast pulse discharge plasma spectroscopy technique (LA-FPDPS), was used for the first time to analyze the Sn concentration in soil. The peak intensity of Sn (284.0 nm) line from soil plasma emission was greatly enhanced in comparison with using the traditional single pulse (SP) LIBS system. Using the technique, calibration curve of Sn in soil was derived. The limit of detection (LOD) for Sn in soil was reduced to be 0.16 microg x g(-1). The value is significantly improved compared with the results reported in literature when using LIBS technique, which usually was between 8.2 to 54 microg x g(-1) depending on the experimental condition, indicating that this technique possibly will be useful for rapid quantitative elemental analysis in soil.
