We studied the interaction of sodiumdodecylbenzenesulfonate (SDBS) with Nile Blue (NB) and Safranine T (ST) bya spectral correction technique. The aggregations of NB and ST on an SDBSsurface obeyed Langmuir isothermal adsorption. The adsorption ratios of NBand ST to SDBS were both 0.5, and the adsorption constants of theaggregates were 1.80 x 105 and 9.49 x 104. Theaggregations were applied to the quantitative determination of aniondetergent in samples; the recovery of SDBS was between 90.3 and 106%together with an RSD of 3.78%.
