| An effective microextraction method has first been developed for concentration of o -phthalic acid ethers from water using ultrasonic dispersion of an extraсtion solvent. Capillary gathering of an extract simplifies its separation and elimi- nates extract losses due to evaporation. Detection limits of five o -phthalates have been achieved at a level of 10-5 - 10-6 mg/l which is not inferior to the world's best results. |
