Embodiment 1
[0022] Such as figure 2 Shown is a flow chart of the present invention for the preparation of nuclear medicine diagnostic reagent-oxygen 18 water. The present invention is used in the preparation method of nuclear medicine diagnostic reagent-oxygen 18 water. First, the raw material of deuterium oxygen 18 double-labeled water obtained by industrial water rectification is added to an electrolytic cell for electrolysis, and the deuterium gas obtained by electrolysis is prepared into heavy deuterium water through a catalytic reaction. Utilize deuterium gas; the oxygen 18 gas obtained by electrolysis first undergoes a catalytic purification process, and then uses a dry adsorption process to obtain high-purity oxygen 18 gas, which is directly catalytically reacted with platinum mesh and high-purity hydrogen at high temperature to directly obtain quality Qualified diagnostic reagent for nuclear medicine - oxygen 18 water.
