Elimination de la Tyrosine par Adsorption sur Différents Matériaux et Effet de la Minéralisation des Eaux

Abstract

The objective of this work is to study the possibilities of tyrosin retention onto various adsorbents (granular activated carbon and powdered activated carbon, activated bentonite, activated alumina,). The literature review has presented the main characteristics of natural organic matter and more particularly amino acids of which tyrosin. The most current techniques of depollution were described while insisting on the process of adsorption on various materials. During the experimental study, the tests carried out on static system and allowed to follow the tyrosin kinetics adsorption on various materials tested on distilled water or mineralized waters. kinetics led to various removal efficiencies of tyrosin.The influence of reactional parameters such as the mass of adsorbent, for a constant mass ofadsorbent, the The best results were obtained for activated carbon. Removal is improved when the medium of dilution is mineralized. An increase in removal is also noted when the masses of adsorbents increase, depending however on the limitations of these.
