| Popis: | Insoluble Ferrocyanide composites prepared for studying 134Cs sorption from aqueous solutions. Two different preparation techniques are used; impregnation /precipitation method (iKCoFC/SG) and core–shell method (mKCoFC/SG). Physico-chemical characterization of the prepared samples is studied by FTIR, SEM, XRD and DTA-TGA. The maximum adsorption capacities towards 134Cs are 14.803, 15.627 mg g−1 for mKCoFC/SG and iKCoFC/SG, respectively at pH 5.5 and 25 °C. The kinetic mechanism of the sorption reaction is applicable with a pseudo-second-order model. The sorption process is favourable. |
