Abstract:
The effect of Sn(IV)-for-Fe(III) substitution on the adsorption of As(V) and on the reactivity in acid media were studied for pure and Sn-substituted goethites. Adsorption isotherms indicated that the As adsorption increases in the Sn-goethites almost duplicating the value of pure goethite. Dissolution experiments showed sigmoidal curves with K rate values that decreased with the Sn(IV) incorporation. The results indicate that the Sn-for-Fe substitution enhances the adsorption of As(V) and stabilizes the oxide towards dissolution in acid media, confirming the usefulness of Sn-goethites in removal technologies. © 2014 Taylor & Francis Group.
