✦ Synopsis

Ultra-violet spectrophotometry has been used for qualitative and quantitative analysis of water and wastewater in conjunction with appropriate signals and a deconvolution method. Application of this procedure with the use of a portable UV spectrophotometer was carried out to study treated wastewater discharge into a river. The data obtained were used to estimate dilution factors of polluted waters at different points of sampling. This simple and rapid methodology can be easily transposed with any PC-controlled UV spectrophotometer including a multicomponent routine.

Schlagwörter: Wasseranalytik, UV-Spektrophotometrie, Kläranlagenablauf, Gewässerüberwachung Zusammenfassung: Die UV-Spektrophotometrie in Verbindung mit einer Methode zur Spektrenentfaltung wurde zur qualitativen und quantitativen Analyse von Flußwasser-und Abwasserproben eingesetzt. Mit Hilfe eines tragbaren UV-Spektrophotometers wurden an einem Fluß Vor-Ort-Untersuchungen in der Nähe eines Kläranlagenablaufs vorgenommen. Mit den erhaltenen Daten wurde der Verdünnungsgrad für die Gewässerverunreinigungen an verschiedenen Probenahmestellen abgeschätzt. Das vorgestellte schnelle und einfache Verfahren läßt sich mit jedem PC-gesteuerten UV-Spektrophotometer durchführen, wenn ein Programm zur Vielkomponentenanalyse zur Verfügung steht.

1. SERCON is a technique for assessing the conservation value of rivers using criteria such as naturalness, physical diversity and species richness. The system may be used with reference to a printed manual or as a computer application. SERCON Version 1 was used for the first time during 1995-1996 t

Determination of the linear range is one of the main concerns in validation of an HPLC analysis method. It is particularly important since single point calibration will be then used routinely. We proposed an iterative methodology to handle this problem. The idea was, at each step, to test statistica
