Abstract EN
In this study, the adsorption removal of an anionic dye (Congo red) by a local bentonite before and after modification was studied.
The modification of the bentonite was made by organophilisation using surfactant (HDTMA) and by pillaring process to obtain a bentonite with Ti pillars and with mixed pillars of Fe/Al.
The various synthesized materials are characterized by different techniques such as DRX, MET, N2 adsorption-desorption, Zeta potential measurement.
Results show the development of the texture and the structure of the bentonite after modification.
The various adsorbents synthesized show an increase in the adsorption capacity of Congo Red compared to the initial bentonite.
Adsorption isotherms are described by the Langmuir model in all cases except that for Ti pillared bentonite, the Freundlich model is more suitable.
Pseudo-second order is better for describing the adsorption process.
Also, regeneration of the adsorbent is approached in this study by photochemical way and the results show a total regeneration of the adsorbent.
