• A Characterization Method of Organic Pollutants in Water by Ultraviolet Absorpsion

抄録

The ultraviolet absorption spectra of aqueous solutions of 86 organic compounds were measured, and the relationships among the absorbances at the peak wave length, 220 nm, 254 nm and 275 nm and the concentrations of TOC, TOD and COD_Mn are discussed for characterization of organic pollutants in water.<BR>Several organic compounds did not show any absorbances, and the aliphatic compounds showed less sensitivities than the aromatic compounds. All the compounds used could be classed in the seven groups by the characteristics of the absorbances at 220 nm (A₂₂₀) and at 275 nm (A₂₇₅) near which various organic compounds showed maximum absorbances. The ratios of A₂₇₅/A₂₂₀, A₂₂₀/TOC and A₂₇₅/TOC seemed to be very useful for characterizations and identifications of organic pollutants in water, though the affections of several inorganic ions such as carbonate, nitrite and nitrate need to take notice. However, the absorbances could not be generally used for evaluation of the values of COD_Mn.
