Application of ultrasound-assisted emulsification microextraction for spectrophotometric determination of trace amounts of antimony(v) in drinking water samples using rhodamine B

Ultrasound-assisted emulsification microextraction (USAE-ME) procedure has been applied for preconcentration and spectrophotometric determination of antimony(V) in water samples. The method is based on the ion-pair formation of hexachloroantimonate with rhodamine B in acidic medium, followed by USAE-ME of the formed ion-pair into fine droplets of the organic phase for spectrophotometric detection. Experimental parameters for both the...
