“…In this respect, many adsorbents have been developed and proposed to deal with these wastes, such as zeolites, porous silica, activated carbon, clay, and resins [3][4][5][6][7]. Besides their application in the nuclear industry, these adsorbents play an important role in the industrial field and primarily those related to the environment; they have also been widely used in the petrochemical synthesis and oil refining [8,9], other diverse applications have significantly increased lately. Among all these porous materials, the aluminosilicateand aluminophosphate-based catalysts and their derivatives have, by far, the best technological impact due to their variety, their catalytic activity, and their behaviour as ion exchangers as well as their selective adsorption property.…”

The present work deals with the investigation of the use of synthesized 4A and P1 zeolites in the adsorption of uranium (VI) ions from liquid effluents (with initial concentrations of 100, 85 and 80 mgÁL À1 ). Batch experiments were performed and the effects of temperature, solid-liquid ratio, pH and initial UO 2 2+ ion concentration were studied, and the optimal parameters were determined. The kinetic and thermodynamic aspects of the process as well as the diffusion mechanism have been studied. The obtained results showed that 4A and P1 zeolites are very effective adsorbents.
