“…25 For the determination of total antimony Sb(III) + Sb(V) in the mixed sample, the 0.10 mol dm -3 Ce(IV) solution was used to convert Sb(III) to Sb(V) before the FI-CL procedure; after the oxidation, the 1.0 mol dm -3 hydroxylamine solution was added to the resultant solution for reduction of excess Ce(IV). For the determination of Sb(V) alone in the mixed sample, on the other hand, this procedure was carried out without the addition of Ce(IV).…”

“…24 In our previous study on the differential determination of Sb(III) and Sb(V), RB was used not only as an extracting reagent but also as a CL reagent in a hybrid analytical method based on the combination of off-line liquid-liquid extraction with a RMM-CL detection system. 25 Sb(V) was transferred as the [SbCl6] -ion from aqueous solutions into toluene in the extraction process involving ion-pair formation of the chloro-complex anion with the RBH + ion. When the Ce(IV) oxidant in the acidic water pools of the reversed micelles of cetyltrimethylammonium chloride (CTAC) in 1-hexanolcyclohexane was mixed with the RB solution in toluene using an FI system, CL emission resulted from the oxidation of RB with Ce(IV) following its uptake by the micelles into the water pools 25,26 and the CL intensity was stronger than that in the usual aqueous solution.…”

“…26,27 As RB is extracted one-on-one with the Sb(V) chloro-anion, the CL intensity is proportional to the amount of RB extracted. 25 Since the off-line extraction process is manually operated and is open, the off-line procedure is relatively tedious, slow, and susceptible to contamination from laboratory wares and the environment. Also, there are plentiful chances for the relatively volatile organic solvent to evaporate before analysis, causing experimental errors and health hazard problems.…”

A rapid and sensitive flow method, based on the combination of on-line solvent extraction with reversed micellar mediated chemiluminescence (CL) detection using rhodamine B (RB), was developed for the determination of antimony(III) and antimony(V) in aqueous samples. The on-line extraction procedure involved ion-pair formation of the antimony(V) chloro-complex anion with the protonated RBH + ion and its extraction from an aqueous hydrochloric acid solution into toluene, followed by phase separation using a microporous membrane. When in a flow cell of a detector, the ion-pair in the extract driven was mixed with the reversed micellar solution of cetyltrimethylammonium chloride in 1-hexanol-cyclohexane/water (0.60 mol dm -3 H2SO4) containing cerium(IV), its uptake by the reversed micelles and the subsequent CL oxidation of RB with Ce(IV) occurred easily, then the produced CL signal was measured. Using the proposed flow method under the optimized experimental conditions, a detection limit (DL) of 0.35 μmol dm -3 and a linear calibration graph with a dynamic range from DL to 16 μmol dm -3 were obtained for Sb(V) with a precision of 1.4% relative standard deviation (n = 5) at the Sb(V) concentration of 8.2 μmol dm -3. The present method was successfully applied to the determination of Sb(V) in water samples and to the differential determination of Sb(III) and Sb(V) in copper electrolyte industrial samples, where total antimony Sb(III) + Sb(V) was determined after oxidation of Sb(III) to Sb(V) with Ce(IV) and Sb(III) was calculated by difference, for which the DL was almost the same as that for Sb(V).

Surface-active agents are organic compounds of amphiphilic nature. When the concentration of surfactants is higher than a certain value, the monomers adhere to form well-defined aggregates known as micelles. These micelles have been employed in flow injection analysis (FIA) for various purposes. In chemiluminescence-based FIA, micelles can improve sensitivity by changing the chemical structures of the reagents, facilitating intramicellar energy transfer, accelerating the reaction kinetics, or stabilizing the excited singlet states. Micelles can improve sensitivity in FIA/ultraviolet-visible by electrostatic or solubilization effects. In FIA/fluorescence, emission intensity is considerably enhanced in micellar media due to the protective environment that restricts nonemissive energy transfer processes. If FIA is coupled with flame atomic absorption, the signals are enhanced with surfactants due to the decreased surface tension that results in the generation of smaller droplets during the aspiration and nebulization processes. In addition, surfactants promote the enrichment of the analyte in the double layer at the air-water interface. The FIA/cloud point extraction technique is based on using surfactants as alternatives to organic solvents. This review discusses the different roles of micelles in FIA methods.
