Adsorption of radioactive elements on alumina and its uses for determination of gross α activity in urine

Radiation Protection Department, Atomic Energy Establishment. Cairo, Arab Republic of Egypt.
On a vérifié l’adsorption sur l'alumine de certains produits de fission et de certains actinides en solution aqueuse et en présence de phosphates. L'étude de l'adsorption en fonction du pH. de la force ionique et de l'âge du radionucléide indiquent le rôle considérable de ces paramètres dans l'interaction entre le radionucléide et la surface de l'alumine. On donne une méthode, basée sur les phénomènes d'adsorption des actinides sur l'alumine, qui permet d'évaluer l'activité α globale dans l'urine.
Abstract
Adsorption of some fission product and actinide elements, from aqueous and phosphate solutions on alumina surface was verified. Studies of adsorption as a function of pH. ionic strength, and age of radionuclide indicated that these variables strongly acted on the interaction between the radiocuclide and alumina surface. A method based on the adsorption phenomenon of actinide elements on alumina was developed in order to determine gross α activity in urine.
