Abstract EN
The objective of this study is to evaluate the efficiency of methylene blue removal using Oued Sebou sediments as an adsorbent.
The presence of carboxyl functional group demonstrated by infrared (IR) analysis of the sediment favorized the methylene blue (MB) adsorption.
Sediment collected from Oued Sebou could remove the most MB molecules at pH 8.
The Freundlich model described suitably the adsorption process.
The experimental measured enthalpy (ΔH) and entropy (ΔS°) are 118.1 kJ mol−1 and 395.2 J mol−1 K−1, respectively, indicating that the reaction was endothermic with an increase of randomness at the solid/liquid interface during the adsorption.
The kinetics of MB adsorption by sediment were adequately fitted to the pseudo-second-order model.
Experimental results showed that the adsorption capacity of the methylene blue dye depends on the solution pH, the initial dye concentration, the adsorbent mass, the sediment particle diameter, and the temperature of the reaction medium.
The removal efficiency of the MB molecules reaches 100% after 60 minutes under the optimum conditions.
