On-line quantitative analysis of heavy metals in water based on laser induced breakdown spectroscopy
Listed in ScienceDB
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.
Description
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.
