AI Technical Summary

Technical Problem

Existing technologies for preparing high-purity 68Ge stock solutions suffer from problems such as difficulty in controlling reaction temperature, difficulty in removing impurity elements, difficulty in separation and purification, and insufficient safety.

Method used

A mixed solution of sodium hydroxide and hydrogen peroxide was used as the leaching solution to leach the irradiated gallium target. The reaction temperature was controlled at 40-50℃, and a round-bottomed container was used for stirring to reduce the dissolution of impurity elements and improve the leaching efficiency and safety of germanium.

Benefits of technology

This effectively reduces the difficulty of separating and purifying germanium leachate, improves germanium recovery rate, ensures the safety of the production process, and simplifies subsequent separation and purification operations.

Abstract

本发明公开了一种金属镓靶中68Ge的溶解浸出方法,包括如下步骤:配制氢氧化钠和过氧化氢的混合溶液,混合溶液中,氢氧化钠的浓度为0.8‑0.9M,过氧化氢的质量百分数为3%‑4%;将混合溶液与经过辐照后的金属镓靶混合,将混合体系加热至40‑50℃,搅拌反应设定时间后,将浸出液与金属镓分离;重复浸出设定次数后,即可。采用本发明的方法溶解得到的溶解浸出液中,68Ge为含氧锗酸盐,沸点高,不会因挥发造成产品损失,可以有效提高68Ge的收率。
