Fate of aromatic sulphonates in fluvial environment

Water samples from the Bormida river in Italy, which is polluted with sulphonated derivatives from the manufacture of azo-dyestuffs, were analysed by fast atom bombardment (FAB)-tandem MS with a solid-phase extraction pretreatment. The results were compared with those obtained with HPLC with combine...

Description
Summary:Water samples from the Bormida river in Italy, which is polluted with sulphonated derivatives from the manufacture of azo-dyestuffs, were analysed by fast atom bombardment (FAB)-tandem MS with a solid-phase extraction pretreatment. The results were compared with those obtained with HPLC with combined UV and fluorescence detection. FAB-MS confirmed the presence of aromatic sulphonic acids detected by HPLC. In addition, FAB-MS detected several sulphonate compounds other than amino and/or hydroxy substituted benzene, naphthalene or anthraquinone sulphonates. These compounds were suspected of originating from the oxidative degradation of naphthalene sulphonates.
