Abstract
A dispersive version of the microextraction preconcentration of organochlorine impurities and aromatic compounds from water has been developed. Carbon tetrachloride (15 ml) has been used as an extractant, and ethanol (1 ml) has been used as a dispersing agent. Coefficients of impurity concentration have been determined. The factors affecting the efficiency of concentration have been studied. The limits of chromatography-mass spectrometric detection of the investigated impurities using microextraction preconcentration were (0.05 - 3) 10-5 mg/liter.
