dc.description.abstractXenon (Xe) is expected to emerge as a highly demanded noble gas globally over the next few years due to its variety of applications in electronics, commercial lighting, medical applications as well as ion propulsion. Xenon noble gas can exist and be extracted in two different states: radioactive and non-radioactive. In the nuclear power industry, radioactive Xenon gases are one of the volatile radionuclides that are released during the reprocessing of used nuclear fuel (UNF). On the other hand, non-radioactive Xenon (Xe) gases are available naturally in the earth’s atmosphere in extremely low concentrations. The conventional method of extracting Xenon (Xe) noble gas from both states involves cryogenic distillation, which is energy intensive and costly. Therefore, an alternative method of using adsorptive separation through Metal Organic Framework is explored and studied for the effective extraction of Xenon (Xe) noble gas. To facilitate a better understanding of the adsorption process involving a Xenon and MOF system beyond the scope of adsorption isotherms and pore size distribution, the thermodynamic properties of entropy and enthalpy are derived alongside properties such as specific heat capacity and isosteric heat of adsorption. The modified Langmuir (LE) equation proposed by Sun and Chakraborty was employed to the experimental isotherm to extract parameters such as isosteric at zero coverage and pre-exponential coefficient which are essential in tabulating the derived properties. Using a graphical representation to analyse the derived formulation at varying pressures and temperatures, the results contribute to an understanding of the characteristics necessary to design an effective Xenon and MOF pair. Furthermore, through the entropy and temperature maps analysis, a typical heat storage system can be represented where the charging and discharging of Xenon (Xe) gas is represented by the change of entropy in a closed loop.en_US
