Abstract Producing compact monoliths of mesoporous uranium oxide that are free from surface active components and able to be wet by highly radioactive solutions is of great interest for future nuclear technologies. In this direction, metastable colloidal sols of UO2 using U(IV) as precursor and carboxylic surfactants (Polyoxyethylene(9) oleyl ether carboxylic acid C16/18:1E9COOH and Polyoxyethylene(10) lauryl ether carboxylic acid C12E10COOH) have been successfully prepared by indirect precipitation for 6 ≤ pH ≤ 8 with a molar ratio between uranium and surfactant U/S (OH) 4-n n+ (1 ≤n≤4 ) and makes the colloidal sol-gel process controllable. The principle shown here that results in partitioning the uranium into molecules, nanoparticles and aggregates could be useful in the design of molecularly dispersed Uranium and Plutonium coming from sol-gel chemistry.

羧酸盐基表面活性剂多层囊泡负载UO2纳米颗粒胶体溶胶

摘要 生产不含表面活性成分且能够被高放射性溶液润湿的介孔氧化铀致密整料对于未来的核技术具有重要意义。在这个方向上，以 U(IV) 为前体和羧酸表面活性剂（聚氧乙烯（9）油基醚​​羧酸 C16/18:1E9COOH 和聚氧乙烯（10）月桂基醚羧酸 C12E10COOH）的亚稳态胶体溶胶已成功制备以铀和表面活性剂 U/S (OH) 4-n n+ (1 ≤n≤4 ) 的摩尔比沉淀 6 ≤ pH ≤ 8 并使胶体溶胶-凝胶过程可控。这里显示的原理导致将铀分成分子，
