Experimental data and assessment of predictive modeling for radium ion-exchange on beidellite, a swelling clay mineral with a tetrahedral charge

The presence of swelling clay minerals, such as smectites, is known to be one of the main parameters controlling the mobility of radium in natural environments due to the high adsorption capacities of these materials. However, experimental data and modeling from literature allowing to investigate th...

Description
Summary:The presence of swelling clay minerals, such as smectites, is known to be one of the main parameters controlling the mobility of radium in natural environments due to the high adsorption capacities of these materials. However, experimental data and modeling from literature allowing to investigate the adsorption properties of radium towards smectite in a wide range of acidic conditions (2
