Ultrasound‐assisted emulsification solidified floating organic drop microextraction was used for preconcentration of trace amounts of bismuth prior to its determination by flame atomic absorption spectrometry. The bismuth ions were extracted by an organic microdrop composed of 1‐dodecanol containing the complexing agent dithizone. The method involves the transferring of the bismuth ion from the aqueous...
A simple and economic analytical method based on low density solvent ion‐pair dispersive liquid–liquid micro‐extraction using high performance liquid chromatography–diode array detection has been used for the determination of phthalic acid, terephthalic acid, and iso‐phthalic acid in aqueous samples. In this work, 0.75 mL methanol (as a disperser solvent), 90 μL toluene (as an extraction solvent),...
