heal.abstractCs-137 and Sr-90, both byproducts of the uranium and plutonium fission processes, make up the majority of high-level waste from nuclear power plants. Ni-63 is a byproduct of the erosion-corrosion process of the reactor components in nuclear energy plants. The concentrations of these ions in solution determine the Waste Class (A, B, or C); thus, their selective removal in the presence of large excesses of nonradioactive ions is necessary to reduce waste volume and cut disposal costs. We report the new material K2xMgxSn3-xS6 (x = 0.5-1, KMS-2) and its application for the ion exchange of Cs+, Sr2+, and Ni2+ in varying conditions. This compound crystallizes in the hexagonal space group P6(3)/mmc with cell parameters a = b = 3.6749(8) angstrom and c = 16.827(4) angstrom. The difference in crystal structure between KMS-2, the previously reported Mn analog K2xMnxSn3-xS6 (KMS-1), and their parent SnS2 is also described. Distribution coefficients for KMS-2 are high for Cs+ (7.1 x 10(3) mL/g) and Sr2+ (2.1 x 10(4) mL/g) at neutral pH (similar to 6 ppm, V/m similar to 1000 mL/g). We also report on the comparative study of Ni2+ ion exchange with both KMS-1 and KMS-2. Additional competitive reactions using Cs+, Sr2+, and Ni2+ in high concentrations of salt solution and at different pH values are reported.en
