Valorisation of wood dates stones of a variety of palm tree of Tinghir region (Morocco): Application to eliminate methylene blue [Valorisation du bois des noyaux des dattes d'une variété de palmier de la région de Tinghir (Maroc): Application à l'élimination de bleu de méthylène]

This work registered under a research of adsorbent,effective and less expensive. we are interested to materials agro ressources as it happens at date stones (ds) of palm tree. the effectiveness of this material is tested using the methylene blue mb. the various parameters influencing the adsorption (contact time,mass of the adsorbent,temperature,ph and initial concentration of the solution) were studied. the study of adsorption isotherms showed that the model of langmuir better describes adsorption of mb on ds.
