“…It is a watersoluble cationic dye and can reveal very harmful effects on living things such as difficulties in breathing, vomiting, diarrhea, nausea and several negative impacts on the aquatic environment [1]. Therefore it is very important to confirm the water quality, since even just 1.0 mg/L of dye concentration in drinking water can impart a significant color, making it unfit for human consumption [2].…”

Abstract. Cationic dye adsorption from aqueous solution onto synthesized geopolymer was investigated by batch and fixed bed column experiments. The geopolymer material was elaborated by alkali solution and fly ash supplied by Jorf Lasfar power plant of Morocco. Physical and chemical characteristics of samples were determined by FX, DRX, SEM, 29 Si MAS NMR and Zeta potential methods. The Brunauer, Emmett and Teller (BET) technique is used to determine the surface area. The Barrett-Joyner-Halenda (BJH) method was performed to obtain pore size distribution curves and average pore diameter. Kinetics data were analyzed using pseudo-first-order, pseudo-second-order and intraparticle diffusion models. To predict the breakthrough curves and determine the main fixed bed column parameters, three kinetic models; Tomas, Bohart-Adams and YoonNelson models are applied to fitting the experimental data. The kinetic study showed that the pseudo-secondorder can be used to describe the methylene blue (MB) adsorption process on the geopolymer matrix. The kinetic models of the adsorption in dynamic column are suitable to describe the continuous adsorption process of dyestuff by the geopolymer. The results of this study indicated that geopolymer derived from fly ash can be used as a low cost effective adsorbent for cationic dye removal from industrial aqueous effluent.

Generally textile effluents are highly coloured, contain non-biodegradable compounds and they have high content of solid wastes, comprising fibres and paper wastes. The discharge of such effluents in the environment is worrying for both toxicological and esthetical reasons. The aim of the present work is to study the performances of the combining microfiltration-adsorption process for the treatment of coloured waters. Methylene Blue (MB) was used as model compound. The effects of significant operating parameters such as transmembrane pressure (TMP) and bentonite concentration on the process performance characterized by flux and rejection factor were investigated. Experiments carried out with Methylene Blue solutions confirmed the potential of this combined process for the treatment of dyed waters. keywords: Bentonite, clay, Methylene Blue, adsorption, microfiltration Estudio del proceso combinado de adsorcion-microfiltracion en el tratamiento de aguas coloreadasNormalmente los efluentes de la industria textil están coloreados y contienen compuestos no biodegradables además de residuos sólidos, fibras y residuos de papel. La liberación de tales efluentes al ambiente es preocupante tanto por razones estéticas como toxicológicas. El propósito del presente trabajo es realizar el estudio de las prestaciones del proceso combinado de adsorción-microfiltración para el tratamiento de aguas coloreadas. Se utilizó Azul de Metileno como compuesto tipo. La influencia de parámetros de operación tales como Presión transmembrana y la concentración de bentonita en el comportamiento del proceso, caracterizado por el flujo del permeado y el factor de retorno que fueron los parámetros estudiados. Los experimentos realizados con las soluciones de Azul de Metileno han confirmado el potencial del proceso combinado para el tratamiento de las aguas teñidas.
