Preparation of Composite Hierarchical Porous Structure of Laboratory Prepared Carbon - Zeolite A to Remove Undesirable Ions from Aqueous Solution as a Method to Remove Radioactive Isotopes

In this research, the hydrothermal process was used to prepare a composite material zeolite-A crystals onto the surfaces of a laboratory-prepared plant waste carbon (the carbonization process was carried out in an inert atmosphere containing nitrogen gas at a temperature of 900 degrees Celsius). These materials were synthesized to form a hierarchal porous structure. The prepared composite material, which consists of carbon produced from the waste of tamarind stone in conjunction with Zeolite-A, was used in this study to investigate the ability of this material to remove the cobalt ion from aqueous solution as a method to remove radioactive isotopes using the batch mode. The composite material was characterized using XRD diffraction and SEM to study the structure and morphology of the product respectively. While, the surface area was measured using the nitrogen gas adsorption method (BET method) at 77 K adsorption. A batch reactor mode was applied to remove Co2+ ions from aqueous solution. It was found that the carbon of TS composite in conjunction with zeolite-A has higher ability to remove the ions of Co2+ than the pure Zeolite A (TSA) synthesized under the same conditions. In summary, the results proved that the composite of Carbon–Zeolite A (TSA) can be used to remove radioactive ions of radioisotopes from aqueous solutions and can be considered as an environmentally friendly alternative.
