Résumé:
Our study entitled “Preparation and physical and mechanical characterization of ceramic
membranes based on DD1 and DD3 kaolins : application in the treatment of a FBB textile dye
solution” has the overall aim of contributing to the valorization of local materials such as the
kaolin from Djebel Debagh through the production of low-cost ceramic membranes that can
be effective and efficient in the supply of drinking water to households.
The development and characterization by XRD and BEM of the ceramic membranes
showed that membranes synthesized from DD3 are better than those obtained from DD1
kaolin, and also mixed membranes with a higher proportion of DD3 than DD1. Sintering
temperatures ranging from 800°C to 1200°C resulted in a DD3 membrane with promising
structural and morphological properties, precisely those obtained at a sintering temperature of
1000°C.
A study of the adsorption capacity of the industrial textile dye Red FBB by the DD3 and
DD1 membranes showed the high efficiency of the membrane synthesized from DD3 with a
maximum retention rate and under operating conditions of pH, initial dye concentration and
adsorbent mass optimized by the experimental design.
