With the wide use of nuclear energy, radioactive pollution has become a public environmental concern. In this study, the sodium dodecyl sulfate modified molybdenum disulfide (SDS/MoS₂) was used to remove Eu(III) and U(VI). The experimental results demonstrated that the uptake of radionuclides on SDS/MoS₂ was dependent on solution pH. The maximum adsorption capacities of SDS/MoS₂ at pH 5.0 were 83.0 mg/g for Eu(III) and 98.4 mg/g for U(VI), respectively. The simultaneous adsorption experiment revealed that the existence of Eu(III) could decrease the capture of U(VI) and vice versa. The main removal mechanism of Eu(III) and U(VI) was the electrostatic attraction. Furthermore, the S groups of SDS/MoS₂ might form complexes with Eu(III) and U(VI), which also increased the elimination of radionuclides.

十二烷基硫酸钠修饰的二硫化钼复合材料对of和铀的吸附

随着核能的广泛使用，放射性污染已成为公共环境问题。在这项研究中，十二烷基硫酸钠改性的二硫化钼（SDS / MoS ₂）用于去除Eu（III）和U（VI）。实验结果表明，放射性核素在SDS / MoS ₂上的吸收取决于溶液的pH值。在pH 5.0时，SDS / MoS ₂的最大吸附容量对Eu（III）为83.0 mg / g，对U（VI）为98.4 mg / g。同时吸附实验表明，Eu（III）的存在会降低对U（VI）的捕获，反之亦然。Eu（III）和U（VI）的主要去除机理是静电吸引。此外，S组SDS / MoS ₂ 可能与Eu（III）和U（VI）形成络合物，这也增加了放射性核素的消除。
