dc.description.abstract A simple and rapid extraction-fluorometric method for the determination of anionic surfactant (AS) at the parts-per-billion (ppb) level is developed. Sodium dodecyl sulfate (SDS), an anionic surfactant after the formation of an ion-associate with acridine orange (ACO), a fluorescent cationic dye was extracted in toluene. The fluorescence intensity (λem : 530 nm,λexc: 480 nm) of the complex is a direct measure of the SDS concentration. The calibration graph is linear in the range of 0-1040 ppb of SDS (in toluene). The relative standard deviation is < ± 7%. The method is applicable to river water, pond water and tap water. It is free from interference from sodium chloride upto 0.5M concentration level, and also from many cations and anions upto a large concentration.      en_US
