Investigation of adsorption properties of modified DD kaolins to microporous material type 13X zeolite in treatment of textile industry effluent: experiments and theoretical approach

Résumé

The textile industry has experienced a great development accompanied by a large production of polluted water released into the environment, which requires a treatment that varies according to the nature of the pollutants. The work carried out aims at testing 13X type zeolites synthesized from Djebel Debagh DD1, DD2, and DD3 kaolins in order to remove dyes and other pollutants from the effluent of the COTITEX textile industry (Batna, Algeria). Several experimental parameters were studied (pH, temperature, initial concentration, mass of adsorbent) and physicochemical characterizations were done on the synthesized adsorbents and the effluent to be treated. The zeolites 13X synthesized from DD1, DD2, and DD3 kaolins were characterized using X-ray diffraction (XRD), Fourier transforms infrared (FTIR), and scanning electron microscopy (SEM). The adsorption experiments were done using the anionic dye present in the effluent and using real textile effluent. The results show that the dye adsorption is efficient and feasible at ambient temperature on the 13X type zeolite synthesized from DD1 kaolin compared to 13X zeolites synthesizedfromDD2 and DD3, with a good discoloration efficiency. Experiments with real textile wastewater showed a significant improvement in the physicochemical characteristics (COD, DBO5, TSS, PO4 3-, and NO2-) compared to the untreated effluent.
