Identification et l’utilisation d’une algue rouge dans le domaine des traitements des eaux

Abstract

In view of the current situation of Covid 19, our work has been limited to a bibliographical study which includes several parts: the first part deals with the problem of pollution and depollution, the second part includes the adsorption pheomenon, hydroxyapatite and activated carbons, the third part describes the generalities of seaweed, and the fourth part is based on the identification of the red algae identified as Corallina elongata.An experimental bibliographical synthesis allowed us to value the chosen red algae due to its structure which is rich in protein and CaCo3 and to evaluate the adsorption capacity according to the different scientific journals and publications which estimate that physically and chemically modified marine algae in comparison with commercial activated carbon have more efficient adsorption capacities. The results obtained from the activation methods applied to these algae show a good adsorption capacity. The same is true for the hydrxyapatite elaborated from marine algae, which presents better capacities than the different activated carbons. The adsorption capacity of these activated algae for different dyes and heavy metals in comparison with other adsorbents taken from the literature proves that this new adsorbent can be used successfully in the depollution and decoloration of textile industry waste water.
