| Résumé:  | Due to the abundant use of anionic surfactants  in  our  life  and  their  disposal  in  the  environment,  the  removal  of  surfactants  from  waste  water becomes necessary. The  present  study  focused  to  the  synthesis  and  application  of  layered  double  hydroxides  and  their  derived  oxides  to  remove  the  anionic  surfactant,  sodium  dodecyl  sulphate  (SDS),  from  aqueous  solution  by  adsorption  and  photocatalytic  degradation  under  UV  irradiation.  The  influencing  of  Zn2+/Al3+  molar  ratio  and    initial    SDS    concentration    on    the    adsorption    and    photocatalytic  degradation  of  SDS  are  studied  and  optimized.  The obtained adsorption data were correlated with Langmuir and Freundlich  isotherms  models.  Equilibrium  studies  indicated  that  the  SDS  removal  obeyed  Langmuir  type  of  adsorption.  Kinetic  data  were  better  described  by  pseudo-second-order  model.  The  photocatalytic degradation of SDS has been found to fit the first-order kinetics according to the Langmuir–Hinshelwood model. |
