Description
Summary:Precolumns packed with C18, PRP1 and sulphonic acid cation exchange materials were used for the online group separation and trace enrichment of industrial wastewater samples. The precolumn fractions were analysed by automated liquid chromatography and diode-array UV-Vis detection. Multisignal plots and three-dimensional spectrochromatograms were used in the identification of the pollutants. The technique was optimized for the analysis of 29 organic compounds in industrial wastewater.
