Abstract
The sorption properties of three titanosilicate materials, AM-4, ETS-4, and Na2Ti2O3SiO4 . 2H2O of different framework structure and cation exchange capacity were studied towards the uptake of uranium from aqueous systems. Selectivity factors were estimated by determining batch distribution coefficient (Kd) and uranium removal (mg) per gram of the exchanger as a function of contact time, uranium concentration and batch factor (solution volume to exchanger mass ratio). The difference in their ability to take up uranium was discussed by in terms of their framework structure and the determination of their cation exchange capacity. Comparisons to ETS-10 have been made.
