Batch Recycle Purification Technological Process of ¹⁸O-H₂O Wate

A batch purification technological process for ¹⁸O-H₂O recycled water is established. The impurities was analyzed firstly. The bacteria and endotoxin in ¹⁸O-H₂O recycled water could be removed by ultraviolet sterilize rand sterile membrane, and soluble impurities removed by multiple cryogenic distillation. This process makes indicators meet the accelerator pharmaceutical production requirements, together with high target and synthesis efficiency. This process, which takes advantages of ¹⁸O-H₂O recycled water produced by accelerator, reduces the cost significantly and utilizes the resources reasonably and efficiently.
