Abstract:	摘要： The sorption capacity of cesium (Cs) and selenium (Se) in crushed mudrock was demonstrated in this study through a 2-site Langmuir model. To employ such a numerical analysis, batch tests were applied in this study in synthetic seawater and groundwater with sorption/desorption kinetic experiments (time-dependent) and different concentrations (10 −2 –10 −7 M). The 2-site sorption models, which correspond to two rate constants ( λ 1 and λ 2 ), might be more adequate than 1-site sorption models in characterizing Cs and Se sorption/desorption according to the least square errors between the numerical analysis and the results of the batch tests. The fitting results showed that a 2-site Langmuir model is capable of appropriately describing Cs and Se sorption in mudrock. Consequently, the sorption capacity was calculated at about 0.06 mol/kg for Cs and at 0.015 mol/kg for Se. 其他題名： J Radioanal Nucl Chem 出版者： Dordrecht: Springer Netherlands 出版日期： 2013-05 出處： Journal of radioanalytical and nuclear chemistry, 2013-05, Vol.296 (2), p.1119-1125 版權： Akadémiai Kiadó, Budapest, Hungary 2012 版權： COPYRIGHT 2013 Springer 識別號： ISSN: 0236-5731 識別號： EISSN: 1588-2780 識別號： DOI: 10.1007/s10967-012-2184-1
