Abstract The interaction of acid (PTCA) with cetyltrimethylammonium bromide (CTAB) has been studied by fluorescence spectroscopy. The fluorescence of PTCA can be greatly enhanced by the addition of CTAB, due to the formation a fluorescent supramolecular compound. Under optimum conditions, the enhancement intensity of fluorescence was proportional to the concentration of CTAB over a range of 0–4.5 µmol L −1 . Its detection limit was 0.057 µmol L −1 , which was lower than reported previously. Compared with other methods that have been reported to determine CTAB, this method has high sensitivity, stability and wide linear range and it can be used satisfactorily for the determination of CTAB in aqueous samples.
