Description
Summary:In this study, removal of 209Po from aqueous media using a natural zeolite as an adsorbent material was investigated. The adsorption experiments were performed by batch technique. The influence of specific process parameters such as initial concentration, pH of solution, contact time and temperature was studied to predict the optimum conditions for effective removing of 210Po. Initial and equilibrium activity concentration of 209Po in solutions was counted by a ZnS(Ag) alpha scintillation counter. Adsorption yield of 209Po onto the zeolite was determined as 90 ± 2% at pH:
