The measurement of the activation energy is an important part of the kinetic study ofuranium-uptaking on Hydrous Titanium Oxide (HTO) from sea water. But the kineticproblem of this process still remains in the exploratory stage, and its measurement ofadsorption activation energy is difficult due to the complexity of sea water system and itslow level of uranium concentration (3 μg U/l). In this paper we propose a methodof measurement of adsorption activation energy which is a simple approximation andcan be directly applicable to natural sea water, according to Langmuir's theory with somesimplified treatment. 相似文献
