电化学方法是一种绿色简便的四价铀制备方法。为了提高四价铀的转化率和其制备速率,本文采用阳离子交换膜分隔阴阳极室,以防止四价铀在阳极的再次氧化,并通过阴阳极液的高速流动增强传质与传热,建立了电解制备四价铀的高效装置。实验测试了该装置的性能,同时还考察了电解 Electrochemical method is a green and simple method of preparation of uranium. In order to improve the conversion rate of tetravalent uranium and its preparation rate, a cation exchange membrane was used to separate the anode and cathode compartments in order to prevent the reoxidation of tetravalent uranium at the anode and to enhance the mass transfer and heat transfer through the high-speed flow of the anolyte and anolyte. Electrolytic preparation of uranium efficient unit. The performance of this device was experimentally tested, as well as the electrolysis
