近几年来,由于日本专家们的努力,从海水中回收铀的技术已取得了显著的进展。有人预计,在不久的将来,利用从海水中回收的铀作核能发电,在日本将变成经济的现实。 由于日本原子能研究所(JAERI)所属高崎辐射化学研究中心和东京大学长期合作研制的结果,目前日本专家开发出一种利用辐射诱发的接枝聚合制备的偕胺肟吸附剂来从海水中回收铀的技术。 海水中铀溶解的主要形式是稳定的三碳酸铀酰络离子UO_2(CO_3)_3~(-4)。利用
In recent years, due to the efforts of Japanese experts, significant progress has been made in the technology of recovering uranium from seawater. It is estimated that in the near future, the use of uranium recovered from seawater for nuclear power generation will become an economic reality in Japan. Due to the long-standing cooperative development of the Japan Institute of Atomic Energy (JAERI) Radiation Chemistry Research Center and the University of Tokyo, Japanese experts have now developed an amidoxime adsorbent prepared by radiation-induced graft polymerization to recover uranium from seawater Technology. The main form of uranium dissolution in seawater is the stable uranyl tricarbonate ion UO_2 (CO_3) _3 ~ (-4). use
