Trace naphthalenesulphonates determination in natural water samples

Abstract The presence of sulphonated derivatives of naphthalene was investigated in river, tap and bottled water samples, by means of HPLC with fluorescence detection and GC-MS, after SPE pre-concentration and, in the case of GC-MS analysis, derivatization. These methods showed detection limits in the low ng/L range, and were capable of providing spectroscopic information on the unknown substances, which were of help for assessing the presence of target analytes in the examined samples. In particular, concentrations ranging from 8.9 to 220 ng/L of 2-naphthalenesulphonate were found in samples of the Italian rivers Po and Sangone, and concentrations of this same substance ranging from 6 to 21 ng/L of were found also in the tap water of the city of Torino, part of which is collected from the river Po. The presence of 2-naphthalenesulphonate at concentrations close to the detection limits of both analytical techniques was also suspected in some samples of bottled water.
