| 中文摘要: |
| An account is given of the thermodynamical characteristics of the adsorption of uranyl complex ions on hydrous titanium oxide (HTO) in NaCl-NaHCO3 solution and in seawater.Determined are the adsorption isotherms and the adsorption density in various pH.The contribution of each component to the adsorption density,the adsorption free energy ΔGads,t,the coulostatic energy ΔGcoul,t,and the cqemisorption potential energy Gchem,t are estimated.The average free energy ΔGads enthalpy change,ΔHads,and entropy change,ΔSads,of the adsorption in this system are -7.33 kcal/mol,6.30 kcal/mol and 45.7 cal/mol K respectively.It is hereof concluded that the complex chemisorption process is spontaneous and thermonegativc. |
