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。
^18O2 gas is prepared from the electrolysis of heavy oxygen heavy water using a set of self-made quartz glass electrolysis system. Under the condition of raw material heavy oxygen heavy water ^18O molar content is higher than 80%, the ^18O2 content of the prepared oxygen gas is determined to be 63.66%, which indicates that the whole electrolysis system is tight. In addition, the requirement of delivering ^18O2 beams from the electron cyclotron resonance ion source can be satisfied by the obtained ^18O2 gas.
