Preparation of High Purity ~(18)O_2 by Electrolysis Method

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.
