摘要：Metronidazole, methyl-2-nitro-5-imidazole-1 ethanol, is a medication once discharged into the water after use can react with living organisms and causing adverse effects to their lives. This kind of residue must be removed from wastewater and the technique adopted in this work is the liquid-solid adsorption. Adsorption of métronidazole from aqueous solutions is carried out on Polyaniline (PANI) synthesized by oxidation with Na 2 S 2 O 8 , using the batch technique (static mode). Different parameters influencing the adsorption of metronidazole on polyaniline are examined (solid/liquid ratio, temperature, pH, concentration, and contact time). The results obtained by the technique of batch show a rapid attachment of polyaniline. The Langmuir isotherm appears the most satisfactory is best suited for modeling the adsorption of metronidazole. In addition, the pH and the temperature does not seem to have any noticeable effect on the adsorption of metronidazole.
