摘要： This study investigates sorption and diffusion of strontium (Sr) in two potential host rocks (granite from Kingman Island and basalt from Penghu Island) by using batch and column methods. According to solid-phase analysis, the sorption component primarily contained iron–magnesium (Fe–Mg) minerals in basalt and granite. Moreover, the distribution coefficient ( K d ) of Sr in various concentrations obtained from batch tests indicated a higher sorption capacity in basalt than that in granite because of the 10 % Fe–Mg mineral content. According to the diffusive results in crushed and intact rocks, it showed that major retardation of Sr depended on the micro-porous structure of tested media, such as decreases of constrictivity and increases of tortuosity. 其他題名： J Radioanal Nucl Chem 出版者： Dordrecht: Springer Netherlands 出版日期： 2015-04-01 出處： Journal of radioanalytical and nuclear chemistry, 2015-04, Vol.304 (1), p.435-441 版權： Akadémiai Kiadó, Budapest, Hungary 2015 版權： COPYRIGHT 2015 Springer 識別號： ISSN: 0236-5731 識別號： EISSN: 1588-2780 識別號： DOI: 10.1007/s10967-014-3889-0
