Algerian natural montmorillonites for arsenic(III) removal in aqueous solution

Zehhaf, A.; Benyoucef, A.; Quijada Tomás, Cesar; Taleb, S.; Morallón, E. (Springer Verlag (Germany), 2015-02)

The adsorption of As(III) from aqueous solutions using naturally occurring and modified Algerian montmorillonites has been investigated as a function of contact time, pH, and temperature. Kinetic studies reveal that uptake ...
