摘要

In this paper the content of wastewater dumed into the River Ebro (Spain) by a factory producing dyes derived from dimethylaniline has been studied. In order to concentrate the samples a liquid-liquid extraction with division of the extract into bases plus neutral and acid fraction (Method 625 USEPA) followed by clean-up has been carried out. The extracts has been analyzed by GC/MS and GC/FID. The expeirments were completed by the measurement of different global parameters. Treatment with ozone was performed at different pH values (acid and alkaline).
