摘要：

The iterative flow reversal approach was used for the liquid/liquid extraction of hydrocarbons from water samples. The proposed mamifold offered the possibility of studying the extraction process continuously and with a single measurement several kinds of analytically useful information could be obtained. Aromatic hydrocarbons were separated effectively from more polar compounds and fifteen different compounds were grouped according to their extraction properties, Synthetic samples were classified using the extraction efficiency at various UV-wavelengths. Natural water samples were also analysed with satisfactory results.
