电解法制备高纯¹⁸O气体

摘要: 采用自行设计制造的石英玻璃电解装置，以重氧重水为原料，通过碱性介质电解法进行了¹⁸O气体的制备，在原料重氧重水¹⁸O的摩尔分数＞80%条件下，最终制得¹⁸O气体中¹⁸O₂含量达63.66%，表明整个电解系统气密性良好。此外，制得的气体能够满足电子回旋共振离子源提供¹⁸O重离子束的实验要求

Abstract: High purified 18O gas is used as the gas ion source material of 18O heavy ion beam; meanwhile, it is also widely used in trace technique, medicine and other fields. In this experiment, 18O gas is prepared from the electrolysis of heavy oxygen heavy water by using a set of self-made electrolysis system, the obtained 18O content is higher than 63.66% under the condition of total oxygen 90.17% and the requirement of various researches can be satisfied.
