Résumé
La présence de colorants dans les effluents industriels constitue un problème important dans plusieurs pays. Les industries qui rejettent de tels composés sont principalement les industries textiles et les industries de pâtes et papiers. La décharge de tels effluents dans le milieu récepteur cause une demande excessive en oxygène et ceux-ci doivent par conséquent être traités avant tout rejet dans l’environnement. Cette étude propose une nouvelle option pour le traitement de ce type de pollution, soit la décoloration par utilisation de structures adsorbantes produites préalablement par électrocoagulation avec des électrodes de fer et d’aluminium. Trois structures ont ainsi été synthétisées dans un électrolyte support constitué de 10-2 mol NaCl•L-1. Les trois structures synthétisées ont été analysées par diffraction des rayons X (DRX) et microscopie électronique à balayage (MEB). Ces analyses ont montré la présence dominante de bayerite (Al(OH)3) dans la structure produite à partir d’électrodes d’aluminium et de magnétite (Fe3O4) et lépidocrocite (γ-FeO(OH)) dans la structure générée à partir d’électrodes de fer. Le composé généré en utilisant les deux types d’électrodes contient, pour sa part, de la bayerite et de la goethite (α-FeO(OH)). Un suivi de la décoloration a été réalisé dans des solutions acides (pHi = 4,8) et alcaline (pHi = 9,8) contaminées par un colorant diazoïque ([Trypan bleu]i = 3,75 mg•L-1). Les résultats obtenus ont montré l’efficacité de ces structures, avec des rendements de décoloration compris entre 94 et 99 %, et un rendement d’élimination de la DCO pouvant atteindre 96 %, selon le pH du milieu.

Abstract
The presence of dyes in industrial effluents represents a serious issue in many countries. This type of effluent is mainly discharged by textile and pulp and paper mill industries. The discharge of such effluents causes excessive oxygen demand in the receiving water and the effluents need to be treated before any discharge. This study describes a new option for the removal of this type of pollutant, which is the decolourization with adsorbing structures generated by electrocoagulation using aluminum and iron electrodes. Three solid structures have been produced in a 10-2 mol NaCl•L-1 electrolyte solution. X-ray diffraction (XRD) and scanning electron microscope (SEM) analyses have shown that the structures produced using aluminum electrodes are constituted of bayerite (Al(OH)3), whereas the structures produced using iron electrodes are principally composed of magnetite (Fe3O4) and lepidocrocite (γ-FeO(OH)). The structures generated with both types of electrodes notably contain bayerite and goethite (α-FeO(OH)). Dye removal assays have been carried out in acid (pHi = 4.8) and alkaline (pHi = 9.8) solutions artifically polluted by diazoic dye ([Blue Trypan]i = 3.75 mg•L-1). The results demonstrated very high dye (94-99%) and COD (≤ 96%) removal yields, these removal percentages being sensitive to the solution pH.
