Micro-scale quantitation of ten phthalate esters in water samples and cosmetics using capillary liquid chromatography coupled to UV detection: effective strategies to reduce the production of organic waste

摘要: 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 UV detection. The included liquid-liquid ultrasonic-assisted microwave-assisted dispersive liquid-liquidmicroextraction, microextraction solidification of floating organic droplets, cloud point extraction. linear range the analytes is from 0.5 50 μg mL−1, detection limits 0.02 ~0.17 mL−1. precision accuracy all intra- inter-day analyses are <5.5%. find that droplet (DLLME-SFO) best method quantification most in water samples cosmetics because its low limit high extraction efficiencies.
