“…InSnS-1 exhibits high dynamic adsorption capacity and large effective treatment volume for neutral solution containing high concentration of Cs + . Such excellent treatment capacity exceeds that of most reported Cs + ion exchangers, e.g., MCC-g-AMP, M/SZMs, PEI/ZnFC 54 – 63 . Notably, hitherto studies on the column separation of Cs + from strongly acidic solutions containing high concentration of Cs + are still rare 16 , 64 .…”

Radiocesium remediation is desirable for ecological protection, human health and sustainable development of nuclear energy. Effective capture of Cs+ from acidic solutions is still challenging, mainly due to the low stability of the adsorbing materials and the competitive adsorption of protons. Herein, the rapid and highly selective capture of Cs+ from strongly acidic solutions is achieved by a robust K+-directed layered metal sulfide KInSnS4 (InSnS-1) that exhibits excellent acid and radiation resistance. InSnS-1 possesses high adsorption capacity for Cs+ and can serve as the stationary phase in ion exchange columns to effectively remove Cs+ from neutral and acidic solutions. The adsorption of Cs+ and H3O+ is monitored by single-crystal structure analysis, and thus the underlying mechanism of selective Cs+ capture from acidic solutions is elucidated at the molecular level.

In the present study, a metal–organic framework ([Zn(bim)2(bdc)]n, MOF‐ZBB) compound was prepared and applied as an adsorbent for the removal of strontium ions from aqueous solutions. The influences of several variables such as pH, contact time, and temperature were studied in batch experiments. The effect of interfering cations (Ca2+, Mg2+, Na+, and K+) on the adsorption behavior was also investigated. The Freundlich, Langmuir, and Dubinin–Radushkevich isotherm models were used for the analysis of equilibrium data. The maximum adsorption capacity by applying the Langmuir equation was 123.451 mg g−1 at 75°C with a pH of 7. The thermodynamic study revealed that the adsorption process is endothermic and spontaneous. The results showed that the pseudo‐second‐order kinetic model for adsorption strontium ions onto MOF‐ZBB better described the adsorption process. Finally, the fixed‐bed column experiments were carried out at different feed flow rates to investigate the dynamic capacity of the adsorption process. The results revealed a decrease of about 80% in the efficiency of the column by increasing the flow rate from 1 to 4 ml min−1.
