抄録

A rapid and sensitive spectrophotometric method for the determination of sodium linear-dodecylbenzenesulfonate (DBS) with 1-pentyl-4-(4-aminonaphthylazo)-pyridinium bromide (PANP) in the presence of sodium dodecyl sulfate (SDS) is proposed. The method is based on the formation of the ion associate of DBS with PANP, and does not require any solvent-extraction procedure. PANP was found to react selectively with DBS to form an ion associate, which caused a new light-absorption near to 416nm. The apparent molar absorptivity of the DBS-ion associate with PANP was found to be 4.6×10⁴ dm³ mol^-1 cm^-1 at 416nm. A calibration graph was linear over the ranges from 0.1 to 2.0×10^-6mol dm^-3 DBS. The relative standard deviation (n=10) for 1.2×10^-6mol dm^-3 DBS was 2.0%. The proposed method can be applied preferably to the determination of DBS in river-water samples.
