Summary: Salt lake brine from Qinghai, China contains abundant cesium resources with large reserves. Ammonium molybdophosphate (AMP) and zirconium phosphate (ZrP) inorganic ion exchangers are effective adsorbents for Cs+ separation and extraction. However, their solubility in water limits their adsorption capacity in aqueous solutions, resulting in difficulties in their use and recovery. This study developed a polyurethane sponge (PU sponge) coated with dopamine-coated AMP and ZrP as an environmentally friendly adsorbent carrier. The AMP/PU sponge showed superior Cs+ adsorption performance compared to the ZrP/PU sponge, reaching saturation at an adsorbent amount of 0.025 g and maintaining an adsorption efficiency above 80% for Cs+ concentrations of 5-35 mg/L. The adsorption process was found to be spontaneous and feasible, with a higher driving force at high temperatures. The interaction between adsorbent and adsorbate was explained using density functional theory calculations. This Cs+ adsorbent provides design guidelines for efficient and selective removal of Cs+.

Summary: The corrosion behavior of 304 stainless steel in molten NaNO3-NaCl-NaF salt and vapor has been studied. The results showed the formation of surface oxides and shedding phenomenon, attributed to the existence of NO2 and NO in the vapor. The corrosion rate in the salt is similar to that in solar salt, indicating the insignificant influence of Cl- and F- on the steel. This study enriches the molten salt corrosion database and provides references for alloy and salt selection in CSP.
