REMOÇÃO DE CORANTE CATIÔNICO UTILIZANDO PÓ DE SEMENTES DE MORINGA oleifera

Abstract

The adsorption of methylene blue dye in aqueous solution was performed using seed powder as adsorbent Moringa low cost. The adsorption equilibrium of the system occurred after 300 min to methylene blue. The adsorption isotherms were analyzed by nonlinear modeling of Langmuir and Freundlich. The adsorption data were better described by the Freundlich model checked both by the values of the correlation coefficient as the agreement between theoretical and experimental results. For the kinetic test, the model that best set the experimental data was the Avrami model. The effect of the concentration tests showed that the adsorption capacity increased with increasing concentration of the adsorbent. The results show that the seed powder moringa oleifera is an effective adsorbent for removal of cationic dyes.
