Abstract Dispersive liquid–liquid microextraction combined with capillary zone electrophoresis–UV detection was developed for analyzing triclosan (TCS) and bisphenol A (BPA) in water, beverage, and urine samples. The factors influencing microextraction efficiencies, such as the kind and volume of extraction and dispersive solvent, the extraction time, and the salt effect, were optimized. A background electrolyte composed of 8 mM sodium tetraborate at pH 9.8 was used as the running buffer. Detection was performed at 214 nm. Under the optimum conditions (sample volume, 5.0 mL; extraction solvent, tetrachloroethane, 22.0 μL; dispersive solvent, tetrahydrofuran, 1.0 mL; extraction time, fewer than 5 s; and without salt addition), the enrichment factors were 110.2 and 82.0 for TCS and BPA, respectively. The linear range was 0.02–2 μg/mL with correlation coefficients of 0.9966–0.9969. LODs were in the range of 4.0–8.0 ng/mL. The environmental water, beverage, and urine samples (at spiking levels of 0.1 and 0.4 μg/mL) were successfully analyzed by the proposed method; the recoveries compared to previous methods were in the range of 81.2–103.3%. As a result, this method can be successfully applied for the rapid and convenient determination of TCS and BPA in water, beverage, and urine samples.
