随着原子能科学技术的发展,萃取法的研究日益广泛,目前不论在规模大至日处理矿石数千吨的铀水冶工厂,或者在精细到以原子数目为计算单位的超微量元素分离的放射化学实验室,萃取法均获得了有效的应用。由于这些分离系统比较复杂,萃取的对象也不仅限于铀、钍与钚等核燃料,还有其他共生金属元素及一系列性质相似的裂变元素的分离,它们所涉及的科学技术问题也较广,因此有关萃取的化学问题极其丰富;一门新的、综合性转强的学科“核燃料萃取化学”正在形成。我们认为,核燃料萃取化学应该有三个组成部分:
With the development of atomic energy science and technology, the extraction method has been extensively studied. At present, no matter in uranium hydrometallurgy plants that process thousands of tons of ores, or radiations that are separated to ultra-trace elements that are fine to the number of atoms Chemical laboratory, extraction methods have been effectively applied. Due to the complexity of these separation systems, the subject of extraction is not limited to nuclear fuels such as uranium, thorium and plutonium, but also to other paragenetic metal elements and to a series of fission elements of similar nature, which involve a wide range of scientific and technical issues The chemical issues concerning extraction are extremely rich; a new and more comprehensive discipline, Nuclear Fuel Extraction Chemistry, is taking shape. In our opinion, nuclear fuel extraction chemistry should have three components:
