Quick Evaluation of Organic Substances in Environmental Water and Tap Water Using Fluorescence and Absorption Spectroscopy

The daily management and inspection of environmental water and tap water requires an easy and quick analytical method to reduce a time-consuming process typically requiring a variety of analytical methods. A UV-Visible spectrophotometer and a spectrofluorophotometer can measure the pollution index of organic substances in the water quickly. The absorption in the ultraviolet region is known to have good correlation with COD (chemical oxygen demand) and the absorbance near 250 nm allows organic substances in the water to be detected. Three dimensional fluorescence spectra have the capability to qualitatively and semi-quantitatively identify liuorescing substances in the water with high sensitivity. In this report, we demonstrate that the use of a UV-Visible spectrophotometer and a spectrofluorophotometer allows evaluating the daily pollution status of environmental and tap water quickly.
