“…The adsorption on sepiolite (98.6, 99.9, 95.2 mg g À1 for acid yellow 194, acid blue 349, acid red 423, respectively) was found to be higher than on activated carbon (49.2, 68.2, 26.3 mg g À1 ) but comparable to that on natural bentonite (24.9 92.729.1 mg g À1 ). High adsorptive capacity (300 mg g À1 ) for the removal of dyes (methylene blue) by clay has been observed by other workers too (Bagane and Guiza, 2000). Sepiolite was also used by Alkan et al (2007) who studied the adsorption kinetics and thermodynamics of reactive blue 221(anionic dye), onto sepiolite in aqueous solution by batch method.…”

“…Pour cela, plusieurs types de traitement ont été proposés par l´osmose inverse, la précipitation/ coagulation des matières colorantes, l'adsorption sur charbon actif, et se sont révélés efficaces mais, dans la plupart des cas, très onéreux (BALLAY et BLAIS, 1998;NEVINE, 2008;RODRIGUEZ et al, 2009). Plusieurs auteurs ont étudié l'adsorption de colorants sur divers matériaux naturels tels que les argiles (ALIAN et al, 2010;ALKAN et al, 2007;BAGANE et GUIZA, 2000;BAGANE et GUIZA 2002;BULUT et al, 2008;CHI et EGGLETON, 1999;ÖZDEMIR et al, 2006;GHOSH et BHATTACHAYYA, 2002;LIAN et al, 2009;REYAD et TUTUNJI, 2003;SCHOONHEYDT et JOHNSTON, 2006;VIMONSES et al, 2009b), les matières agricoles : bagasse (MALL et al, 2006), épis de maïs, coquille de noix, etc., et certains rejets industriels : déchets de laine (PERINEAU et al, 1983), cendres volantes, (BHATNAGAR et MINICHA, 2006;EL GEUNDI, 1990) boues de haut fourneaux (ALLEN et KOUMANOVA, 2005) en raison de leurs disponibilités et leurs faibles coûts par rapport au charbon actif.…”

“…Due to their low biodegradability, dyes are generally removed from aqueous solutions by sorption process using activated carbon [7][8][9][10][11]. The cost of this process led to several studies on alternative removal methods by use of less expensive natural materials and waste by-products such as sludge, perlite, rice husk, sawdust, bentonite, organophilic bentonites and layered double hydroxides [12][13][14][15][16][17][18][19].…”
