| titleOfInvention | Rapid atomic fluorescence spectroscopy heavy metal and trace element detection method based on laser ablation plume |
| abstract | The invention discloses a rapid atomic fluorescence spectroscopy heavy metal and trace element detection method based on laser ablation plume. The method comprises the following steps: cleaning a crop sample by using deionized water, and placing the cleaned sample on a sample table; forming 355nm laser by a first path of laser after passing through a three frequency generator, and after a light path is raised, focusing the laser at a position above the sample table to beat the surface of the sample to form the high-density plume; beating the high-density plume from the upward side of the sample by a second path of laser so as to enable atoms to be motivated; acquiring an atomic spectrum of the crop sample, and selecting four spectral lines which are self-absorptive, self-reversal and highest in strength from characteristic spectral lines according to to-be-tested heavy metal and trace elements; establishing a plurality of kinds of multiple regression models by using a sample reference value as output and the spectral line strength as input, selecting four optimal models from multiple regression models, and establishing a comprehensive model; and acquiring four spectral line strength values, inputting the four spectral line strength values into the comprehensive model aiming at the to-be-tested crop sample, and computing the contents of the heavy metal and trace elements of a crop. |
