Abstract
A method for detecting and identifying 23 aromatic sulphonates in natu ral waters was optimized. Samples were pretreated by solid-phase extra ction in order to eliminate interferents and to preconcentrate the ana lytes. Separation of the extracted analytes was accomplished by ion-pa ir HPLC with fluorimetric detection; the eluent composition and pH wer e optimized. The detection limits lie in the low mug l-1 range. Some o f the investigated compounds were found in the water of the river Borm ida (N.W. Italy). Unknown components were identified from their fluore scence spectra.
