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摩尔分数达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。 Using a quartz glass electrolysis device designed and manufactured by ourselves, heavy oxygen and water were taken as raw materials to prepare 18O gas through alkaline medium electrolysis. Under the condition that the molar fraction of oxygenated heavy water 18O was more than 80%, 18O gas was finally obtained In the 18O2 mole fraction of 63.66%, indicating that the entire electrolysis system, airtight well. In addition, the prepared gas can meet the experimental requirements of electron cyclotron resonance ion source to provide 18O heavy ion beam.
