铀和铀系元素在海洋地球化学,海洋地质学以及资源利用的研究中占有十分重要的位置。许多国家很早就开始了海洋铀化学的研究。四十年代,主要的任务是寻找适宜的化学测试方法;五十年代之后侧重于调查和研究其分布规律和存在形态,筛选各种提铀的吸附剂以及发展先进的物理测试技术和方法——中子活化技术、α谱仪和同位素稀释方法等。目前,在化学分离方法和核子测试手段发展的基础上,一方面精确地测定了不同海
Uranium and uranium series elements play a very important role in ocean geochemistry, marine geology and resource utilization research. Many countries have long been involved in the study of marine uranium chemistry. In the 1940s, the main task was to find appropriate chemical testing methods. After the 1950s, the research focused on investigating and studying its distribution and existing forms, screening various adsorbents for uranium enrichment, and developing advanced physical testing techniques and methods - Neutron activation technology, α spectrometer and isotope dilution methods. At present, based on the development of chemical separation methods and nuclear test methods, on the one hand, different sea
