离子交换树脂是目前有着广泛用途的化工产品之一;它无论在工业上或科学研究中均获得了广泛地应用,已成为工作中一种不可缺少的重要工具。近十几年来,由于原子能工业的迅速发展,离子交换树脂在吸收与分离放射性物质(放射性同位素,铀的提炼与纯化,堆回路中水的净化等)方面亦已得到了重要的应用。但是这些化学过程均是在强射线作用下进行的,由于射线与物质的相互作用会产生各种化学变化,因而给离子交换树脂的性能带来一定程度的改变。为了阐明射线作用的影响,以便在原子能工业中广泛地应用离子交换树脂,因此有必要研究各种离子交换树脂的辐射稳定性问题;即研究离子交换树脂的各种不同化学结构以及所处的物理状态与其辐射稳定性的
Ion exchange resin is one of the widely used chemical products at present. It has been widely used in industry and scientific research and has become an indispensable and important tool in the work. In recent decades, due to the rapid development of the atomic energy industry, ion exchange resins have also been used in important applications in the absorption and separation of radioactive materials (radioisotopes, uranium refining and purification, water purification in reactor circuits, etc.). However, these chemical processes are carried out under the action of intense radiation. Due to the interaction between the radiation and the material, various chemical changes will occur, which will change the performance of the ion exchange resin to some extent. In order to elucidate the effect of radiation in order to widely use ion exchange resins in the atomic energy industry, it is necessary to study the radiation stability of various ion exchange resins; that is, to study the different chemical structures of ion exchange resins and the physical State and its radiation stability
