Abstract
With the continuous progress of the national economy and of science and technology, gold plays an increasingly important role in social production and life. The existing detection technology for gold has the disadvantages of heavy pollution and high cost. As an emerging material detection technology, laser-induced breakdown spectroscopy has many advantages, such as low pollution, low cost, rapid detection, and online detection. In this paper, nanosecond lasers and spectrometers are used as the main tools to study the application of laser-induced breakdown spectroscopy in the field of gold element detection. Experiments have found that, under the action of a nanosecond laser with a wavelength of 1064nm, the plasma spectrum of gold has a sharp characteristic spectrum near 242.8nm, which points out the direction for the laser-induced breakdown spectroscopy technology to be used in gold mine detection.
