Ein Beitrag zur Bestimmung von Anilin/Phenol in Wasser/Abwasser mittels UV‐Derivativspektroskopie. Teil 1: Das analytische Grundverfahren

摘要

AbstractUltraviolet derivative spectroscopy was used as an analytical tool for the direct and simultaneous determination of aniline and phenol in water. It is shown that the diA/dλivalues are proportional to aniline (i= 2, 4) and phenol (i= 2, 4 and 5) concentrations at 205.3 or 271.6 … 282.8 nm. The performance characteristics are discussed in detail. Thus the best precision resulted in both aniline and phenol for the second derivatives. The accuracy of the methods applied is independent on the derivative order and concentration levels within the dynamic range of 1 to 10 mg · 1−1aniline or phenol respect
