Abstract:
The interaction of poly(diallyldimethyl ammonium chloride) (PDDA) with dodecyl benzene sulfonic acid sodium (DBS) has been studied by fluorescence spectra. The fluorescence of DBS can be greatly enhanced by addition of PDDA, owing to the interaction between PDDA and DBS. The enhancement intensity of fluorescence was proportional to the concentration of DBS over the range 2.5x10(-7) to 9.6x10(-5)molL(-1). Its detection limit is 3.5x10(-7)molL(-1). The method has high sensitivity and selectivity and was applied to the determination of trace amounts of DBS in water samples with satisfactory result.
