Efficient trapping of cesium ions in water by titanate nanosheets: experimental and theoretical studies

In recent years, TNS has attracted wide attention because of its simplicity in synthesis and high efficiency in ion exchange. The adsorption of cesium ions in aqueous solution by TNS was investigated in this study. Results show that the removal rate of Cs (I) is about 88% when pH = 5.00 ± 0.05, C0 =...
