摘要: It plays a very important role for characterizing sorption behaviors of cesium (Cs) and selenium (Se) on Taiwanese mudrocks to retard the migration of radionuclides from a radioactive waste repository. In this study, two non-linear heterogeneity-based isotherms, Langmuir–Freundlich model (LF) and generalized-Freundlich model (GF), were applied for the evaluation of the sorption characteristics of Cs and Se on Taiwanese mudrocks. The batch sorption experiments were carried out and the experimental data were simulated by LF and GF heterogeneity-based isotherm models. In addition, the results showed that both of the LF and GF models could fit the experimental data more perfectly than the Langmuir one. The heterogeneity of sorption behaviors for Cs and Se could be well characterized by the LF and GF models from the root mean square error calculation and plot of the affinity spectrum. The results demonstrated that the sorption mechanism of Cs and Se on mudrock is quite different and Cs sorption is more heterogeneous and complicated than that in Se. 其他題名: J Radioanal Nucl Chem 出版者: Dordrecht: Springer Netherlands 出版日期: 2013-11 出處: Journal of radioanalytical and nuclear chemistry, 2013-11, Vol.298 (2), p.749-754 版權: Akadémiai Kiadó, Budapest, Hungary 2013 版權: COPYRIGHT 2013 Springer 識別號: ISSN: 0236-5731 識別號: EISSN: 1588-2780 識別號: DOI: 10.1007/s10967-013-2458-2
