Abstract

Time Resolved Laser-Induced Fluorescence Spectroscopic System (TRLIFS) and Time Resolved Laser-Induced Breakdown Spectroscopic System (TRLIBS) have been developed in order to detect the speciation and colloid generation of heavy metal ions in groundwater. The stability constants of humic acid and its chemical analogues with Eu were estimated by TRLIFS. The concentration of Eu colloids was measured by TRLIBS.
