The invention discloses a laser-induced breakdown spectroscopy (LIBS) water quality identification system, which solves the problems that periodic identification is difficult to perform, river pollution cannot be effectively and timely monitored and ecological construction requirements cannot be met in the prior art. The LIBS water quality identification system comprises a rotating disc, wherein asample groove is formed in the rotating disc, a placement platform is arranged in the sample groove, and a baffle block used for supporting or leaving the lower portion of the placement platform is arranged below the sample groove; and a sampling position, a collecting position and a separating position which are positioned on a rotating path of the sample groove are arranged on the rotating disc, a water pipe used for injecting a water sample to be detected is arranged right above the sampling position, laser used for focusing the water sample and forming plasma and a spectrograph used for analyzing a plasma emission spectrum are positioned at the collecting position, and a movable classification platform is arranged right below the separating position. The LIBS water quality identification system achieves the effect of integrated rapid online identification of water quality.
Description
technical field [0001] The invention relates to the technical field of water quality identification devices, in particular to a laser-induced breakdown spectroscopy (LIBS) water quality identification system. Background technique [0002] In recent years, with the rapid development of China's economy, as an important medium for industrial development, river pollution has become increasingly serious. Water quality appraisal has always been based on monitoring by the environmental department, but this monitoring method is not perfect. Although the methods of scientific and technological identification are mentioned, most of them belong to regular identification, which cannot make effective and timely monitoring of river pollution. This kind of monitoring method can no longer meet the needs of ecological construction. [0003] Such as figure 1 with figure 2 As shown, the laser-induced breakdown spectroscopy (laser-induced breakdown spectroscopy, LIBS) technology is an emis...
