建立了一套18 O-H 2 O 回收水批量回收纯化处理工艺。该工艺对18 O-H 2 O 回收水中的杂质进行了分析，通过紫外杀菌，无菌滤膜过滤除去了菌类和细菌内毒素，通过三次低温蒸馏或 C-18柱-二次低温蒸馏除去了可溶性无机和有机杂质，同时保证了同位素丰度符合要求，使18 O-H 2 O 各项指标达到了加速器药物生产要求，并可达到较高的打靶和合成效率。该工艺的建立可以充分利用一次打靶后的18 O-H 2 O 回收水，大幅度降低了成本，资源利用更加合理，高效。

A batch purification technological process for 1 8 O-H 2 O recycled water is established.The impurities was analyzed firstly.The bacteria and endotoxin in 1 8 O-H 2 O recycled water could be removed by ultraviolet sterilize rand sterile membrane,and solu-ble 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 1 8 O-H 2 O recycled water produced by accelerator,reduces the cost significantly and utilizes the resources reasonably and efficiently.
