The specfrophotomefric determination of zinc (Zn2+) in water samples by Flame Atomic Absorption Spectrometry (FAAS) was studied in micellar media of Sodium dodecyl sulfate (SDS), cetylfrimethyl ammonium bromide (CTAB), and polyoxyethylene(10)isooctylphenyl ether (TX100). The effects of the nature and concentration of surfactants on the analytical signal of the Zn2+ were investigated and optimized. The limits of detection (LODs) 0.4, 0.2, and 0.3 ppm for Zn(2+)are SDS, CTAB, and TX100 respectively. The sensitivity and selectivity were largely increased in SDS micellar media. The proposed method was applied to the determination of Zn2+ in distilled water samples by using SDS.
