本稿是以执笔人为首的一个离子交换(I.E)科研集体的介绍。60年代初,笔者任南开大学放化教研室主任期间,选定了离子交换(I.E)为长期的研究对象。这是因为当时国内的核科技需要应用和发展I.E技术;同时,我国的I.E树脂合成技术已有了相当的基础。在前辈科学家的鼓励下,我们从铀水冶中I.E技术的研究入手,较深入的研究了UO_(2-)~(2+)-SO_4~(2-)络合体的 This manuscript is based on the author of an ion exchange (I.E) research collective introduction. In the early 60s, when I was director of the radiology department of Nankai University, selected ion exchange (I.E) as the long-term research object. This is because at that time, China’s nuclear science and technology needed to apply and develop the I.E technology. At the same time, the I.E resin synthesis technology in our country had a good foundation. Encouraged by our predecessors, from the research of I.E technique in uranium hydrometallurgy, we have studied deeply the complex of UO_ (2-) ~ (2 +) - SO_4 ~ (2-) complex
