Abstract Based on laser induced breakdown spectroscopy data analysis, a quantitative determination method of elements was introduced. This method takes the advantage of Fourier analysis to study different part of the spectrum-white noise, thermal radiation and emission spectral lines. Through band-pass filter, emission spectral lines and most noise were separated, only a little white noise was missed. By calculated similarity between detected line and its corresponding unit characteristic line, convolution intensity was introduced to measure the detected line intensity. With Cu 324.75 nm as the analysis line and Ti 337.28 nm as the base line, the way of separating spectrum mentioned before was carried out to detect trace Cu pollution in soil. Results contained two bright spots. First, The correlation coefficient between Cu concentration and the spectral intensity was up to 0.997 9. Last but not the least, the detectability of Cu in soil was 44 mg·kg-1, which is below the trace element thresholds for Class 2 soil used in the environmental quality standard for soil in China. At the same time, the relative error is always below 10%. Therefore the feasibility of this method for portable and instant detection of heavy metals in polluted soil was verified.
