Three different concentrations of H 2 SO 4 (i.e., 3, 5, and 10 N) were used for the activation of 50 g bentonite. The treatment was conducted in a water bath (95–98°C, atmospheric pressure) and 250 ml H 2 SO 4 was slowly added while the mixture was agitated at 400 rpm using a magnetic stirrer. After 2 h, samples were washed (i.e., pH 7) with ...

Activation mitigates concentrated salinity effects on bentonite adsorption affinity only slightly. Therefore, to enhance the Cs and Sr adsorption performance under such conditions, e.g. seawater, a suggestive approach could be to couple bentonite salt-activation with selective complexation, e.g. using hexacyanoferates for Cs uptake.
