Detection of Cu and Cr in the Soil of Navel Orange Plantation in Gannan by LIBS
In order to detect the heavy metal in the soil of navel orange plantation land in Gannan based on laser induced breakdown spectroscopy (LIBS), LIBS and atomic absorption experiments are performed on the samples collected from 16 different areas in Xinfeng an Anxi county of Gannan to detect the Cu and Cr elements. From the information of spectral intensity, signal to background ratio and real concentrations of Cu and Cr in different areas, the lowest concentration of Cu and Cr in the soil gained in atomic absorption experiment are 3.179 μg/g and 6.524 μg/g, respectively, while their spectral intensities in elements are both very obvious. And the relative standard deviation (RSD) in LIBS are all around 10%. However, in-depth experimental study to eliminate matrix effects and new methods for data processing should be done for quantitative analysis.
