Abstract:The preferential exchange uptake of the cations Cs+, Ba2+ and Zn2+ from pure solutions by zeolite-13X follows the order Qinfin [Cs+]>Qinfin [Ba2+]>Qinfin [Zn2+], while in case of binary mixtures the order is Qinfin [Ba2+(Zn2+)]>Qinfin [Ba2+(Cs+)]>Qinfin [Cs+(Zn2+)]>Qinfin [Cs+(Ba2+)]>Qinfin [Zn2+(Cs+)]>Qinfin [Zn2+(Ba2+)]. Ba2+ uptake from mixtures shows the least suppression effect.
