- •
The metallic species which modified the zeolite change the textural properties.
- •
The pHpzc is acid for ZUSCeFe and neutral for ZUSNa.
- •
The Linear model describes the Ba2+-like 226Ra2+ sorption by ZUSNa and ZUSCeFe.
- •
Kd is highest for Ba2+- like 226Ra2+-As(V)-F- solution in contact with ZUSCeFe.
- •
The ZUSCeFe remove simultaneously Ba2+-like 226Ra2+, As(V) and F−.
