[Extraction of trifluralin from acetonitrile solutions].
Results of extraction of trifluralin from an aqueous acetonitrile solution using various organic solvents are presented. The degree of extraction was shown to depend on the nature of extractant and the water/acetonitrile ratio. An optimal electrolyte and the degree of saturation of the water-acetonitrile layer with this electrolyte were selected. The highest efficiency of extraction was achieved by using water-saturated ethylacetate as an extractant. The indices of extraction were calculated as necessary for the isolation of a given amount of trifluralin from aqueous acetonitrile (4:1) solutions with the solvents considered in the present study.
