    Thermodynamic Analysis of Radioactive Pertechnetate Oxo Anion Adsorption
    (Konya Technical University, 2020) Demir, Fatih; Lacin, Omer; Bastaban, Burak
    The aim of this study is to investigate thermodynamics of radioactive pertechnetate okso anion (99mTcO4-) over the active carbon using the adsorption technique in batched systems. According to the obtained results thermodynamic parameters are calculated as ?Ho=0.346 kJ.mol-1, ?So=0.029 kJ.mol-1, ?Go= -7.92 (15oC) ile -8.78 (45oC) kJ.mol-1, ?Hx=0,28 kJ.mol-1 and also the temperature at which the standart free energy value equals to zero calculated as 12 K. These results indicated that the adsorption process is physical and endothermic and at temparatures over 12 K adsorption will take place spontaneously and favorably. In conclusion, it can be said that the results obtained from the thermodynamic analysis of radioactive technetium (which may cause cancer if the limit is exceeded) over the active carbon can contribute to the design of an industrial facility.
