Domestic bottled water samples have first been analyzed and compared with foreign ones. The sources of o- phthalates in water are found. Gas chromatography-mass spectrometry determination of o- phthalates using microextraction with ultrasonic dispersion of the extragent developed by the authors has made it possible to achieve the detection limits of five o- phthalates at the level of 10 |
