Tritium gettering from air with hydrogen uranyl phosphate

Hydrogen uranyl phosphate (HUP), a solid proton electrolyte, getters tritium gas and water vapor from air by dc electrical action. We have reduced the formation of residual tritiated water to less than 2% and demonstrated that HUP can clean a 5.5 m3 working glove box. Data are presented to illustrate the parameters of the gettering and a model is derived. Two other tritium gettering electrolytes have been discovered
