Etude exprimentale de l'élimination de l'orange de méthyle et du bleu turquoise par adsorption -microfiltration

Abstract

Abstract The purpose of this work is to treat industrial liquid waste with several pollutants such as dyes widely used in the spinning, textile and pharmaceutical industries. Where we used two adsorbents the first is chemical (activated carbon) and the second is natural (cactus).To eliminate two pollutants (methyl orange and turquoise blue) by coupling the adsorption, microfiltration and microfiltration-adsorption processes. In this study, we discussed several experimental starting by defining the adsorption conditions(the effect of time and the mass, the acidity of the solution).And then an in-depth study was conducted on the separation of these dyes by the two methods adsorption and adsorption-microfiltrationby (the flow of the treated solution, to determine the variation of the concentration and the pH) as a function of time.The results obtained allow us to conclude that the process of coupling of the adsorption-microfiltration is very effective to eliminate the dyeing.
