Abstract :
[en] Fast quantitative analysis of lead in the simulated soil made of chemical reagents (PbC12，SiO2，CaCO3 and KBr)was carried out with the laser—induced breakdown spectroscopy．
The result shows that the signal—to—noise ratio increases and then decreases with the time delay． The calibration curves of Pb content were constructed with the spectrogram acquired in
experiments．It is found by the investigation that the average relative error of the method for the
fast quantitative analysis of lead in soil is 8．33 and the minimum detection limit is 89 ug／g．
The experimental result proves LIBS is capable of being used in the detection of lead in soil．
