Nano-composites were synthesized by the reaction of waste polystyrene (PS) and KMnO. The structure of the composite was controlled by the solvent/non-solvent system and the concentration of KMnO. The FTIR spectra indicated the functionalization of PS and the attachment of NMO with the polymer chains. The maximum adsorption capacities (q) were 10,000 and 5000 Bq g, for U and Th respectively. Different but controllable sorption/desorption behaviours were noted between Th and U, which could be promising in the separation of Th and U from their mixture.
通过废聚苯乙烯（PS）与高锰酸钾（KMnO₄）反应合成了纳米复合材料。复合材料的结构由溶剂/非溶剂体系以及高锰酸钾的浓度控制。傅里叶变换红外光谱（FTIR）表明了聚苯乙烯的功能化以及N - 甲基氧化合物（NMO）与聚合物链的连接。铀（U）和钍（Th）的最大吸附容量（q）分别为10,000和5000 Bq g⁻¹。钍和铀之间观察到不同但可控的吸附/解吸行为，这在从它们的混合物中分离钍和铀方面可能很有前景。
