Abstract

A UV (266 nm) laser-induced fluorescence (LIF) system with high sensitivity has been used to record fluorescent spectra (300 nm - 700 nm) of various water samples, such as distilled, tap and river water. Large fluorescence peaks corresponding to the fluorescence of Dissolved Organic Compounds (DOCs) were observed in river samples. Significant differences in spectra between different brands of drinking and distilled bottled water were also observed. The LIF system is currently used to measure the trace species in water processed by Reverse Osmosis Water Purification Unit (ROWPU). Initial spectra of the input and output water are presented.
