Removal of cesium ions from aqueous solution by adsorption onto local Taiwan laterite

Kinetic and equilibrium studies of cesium adsorption on ceiling tiles from aqueous solutions

“…The three parameters Langmuir-Freundlich model q, b and 1/n were calculated by performing a non-linear regression to the experimental data using Eq. (11). The parameters are listed in Table 2.…”

“…Adsorption of Cs by soil and minerals has been published in the literature [10][11][12][13][14]. Duursma and Eisma [15] reported that Cs enters the interlayers of a mineral such as illite, since its ionic radius matches the interlayer space of the mineral.…”

An isotope dilution–precipitation process for removing radioactive cesium from wastewater

“…As a result, non-precipitation methods like ion-exchange have been investigated as possible methods to remove radioactive cesium from wastewater [1][2][3]. Natural and synthetic zeolites have been analyzed for their ion-exchange properties with cesium for decades.…”

Efficient removal of cesium from low-level radioactive liquid waste using natural and impregnated zeolite minerals

“…Due to their high cation-exchange capacities and selectivities for Cs, Ba and Sr was, as demonstrated first by Ames [14,15], clinoptilolite and mordenite containing rocks can retard the migration of radionuclides occurring in solution as simple cations and thus are considered as potential hosts for radioactive waste disposal [16][17][18]. Cement encapsulation is the preferred waste for zeolite loaded with Cs and Sr radioisotopes, and some work on clinoptilolite/cement composites has described the importance of the presence of calcium ions to the leaching characteristics of this waste [19][20][21][22].…”
