We have extracted ten phthalate esters (C1 to C8) using six different micro-scale methods for extraction, and then separated them by capillary liquid chromatography coupled to UV detection. The methods included liquid-liquid extraction, ultrasonic-assisted extraction, microwave-assisted extraction, dispersive liquid-liquidmicroextraction, dispersive liquid-liquid microextraction solidification of floating organic droplets, and cloud point extraction. The linear range of the analytes is from 0.5 to 50 mu g mL(-1), and the detection limits range from 0.02 to similar to 0.17 mu g mL(-1). The precision and accuracy of all intra-and inter-day analyses are <5.5%. We find that dispersive liquid-liquid microextraction solidification of floating organic droplet (DLLME-SFO) is the best method for quantification of most phthalate esters in water samples and cosmetics because of its low limit of detection and high extraction efficiencies.
