Descripción
The capabilities of several phosphonium-ionic liquids (PILs) to form ion-pairs with a complex obtained by reaction of arsenate species with molybdate were evaluated. Phosphonium-ILs containing the tetradecyl(trihexyl)phosphonium cation but different anions (dicyanamide and decanoate) and tributyl(methyl)phosphonium methylsulphate IL were studied. Size, polarity and localization of charges in PILs cations showed to influence their capability to form ion-pairs with arsenomolybdate (AsMo12O403-) complex and to extract As(V). The performance of PILs was compared with that showed by a widely used ion-pairing reagent such as cethyltrimethylamonium bromide (CTAB). Finally, the IL tetradecyl(trihexyl)phosphonium dicyanamide was chosen to develop a liquid-liquid microextraction (LLME) procedure using only 80 μL of tetrachloroethylene as extractant. The organic phase was directly injected into the graphite furnace of an electrothermal atomic absorption spectrometer (ETAAS) for As determination. An extraction efficiency of 100% and a preconcentration factor of 130 were obtained with 5 mL of sample. The detection limit was 1.9 ng L-1 and the relative standard deviation for six replicate measurements of 1.0 μg L-1 for As were 4.9%, 5.0% and 5.1% for As(V), As(III) and organic As species, respectively.
