在核燃料后处理的水法工艺中,通常用萃取法和离子交换法回收铀、钚等放射性元素。为抑制萃取过程中的乳化和界面污物的形成以及离子交换中的树脂中毒,料液必需先经除硅处理。本工作结合实际任务,对高酸度硅含量较低的电解质溶液中硅的形态及其聚合动力学进行了研究。
In the nuclear fuel aftertreatment of water processes, extraction and ion exchange are commonly used to recover radioactive elements such as uranium and plutonium. In order to inhibit the emulsification during the extraction process and the formation of interfacial contamination and resin poisoning in ion exchange, the feed liquid must first be silicon-removed. In this work, the morphology and polymerization kinetics of silicon in electrolyte solution with high acidity and low silicon content were studied.
