| Résumé: | The large amount of surfactants discharge into wastewater are harmful for both terrestrial and
aquatic life; in fact the removal of surfactants from wastewater becomes necessary. The present
study is focused on to the removal of sodium dodecyl sulphate surfactant (SDS) by adsorption and
photocatalytic degradation using Zn(2)Al-LDH and TiO2/Zn(2)Al-LDH materials synthesized by coprecipitation.
The experimental adsorption data obtained were evaluated using Langmuir
Freundlich and Temkin isotherms models. The photocatalytic degradation activities of SDS at
different concentration in the range of (10−100 mg/L) over Zn(2)Al-LDH and TiO2/Zn(2)Al-LDH
follows the pseudo first-order kinetics in accordance with the Langmuir Hinshelwood model. The
results indicated that TiO2(3.6)/Zn(2)Al-LDH show the highest photocatalytic activity compared to
Zn(2)Al-LDH sample |
