2022-10-13 On-line quantitative analysis of heavy metals in water based on laser induced breakdown spectroscopy doi:10.57760/sciencedb.03442 en A method for heavy metals determination in industrial wastewater based on laser induced breakdown spectroscopy (LIBS) technique was studied，and the on-line monitoring system which used automatic graphite enrichment and spatial plasma confinement detection was developed and field demonstrated. The limits of detection (LOD) of heavy metal elements(Cd, Cr, Cu, Ni, Pb, Zn) could reach several μg/L. In Tongling, the on-line heavy metal monitor was field demonstrated. The calibration curves of Copper and zinc were built on-site, and then on-line monitoring was conducted. The measurement results by this monitor was compared with ICP-OES, and had a good correlation.  laser induced breakdown spectroscopy (LIBS); industrial wastewater; on-line monitor; field demonstration Nanjing Zhao Deshuo Meng Yao Jia Mingjun Ma Li Fang Jianguo Liu Wenqing Liu PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset Science Data Bank
