  • Method of purification for recycling of gallium-69 isotope
    Patent number: 9102997
    Abstract: A method of purification for recycling of gallium-69 isotopes includes processes of proton irradiation and dissolution for a silver alloy plating target with gallium-69. After the proton irradiation and dissolution, a high concentration elution liquid of gallium-69 and germanium-68 is obtained by washing through an ion-exchange resin to filter out gallium-69 solution, followed by neutralizing precipitation, drying, and sintering treatments to obtain a gallium oxide. The gallium oxide can be dissolved to produce a solid target, and the washing processes can be repeated. The solid target after use can be placed in recycling again. This method is not only implemented to reduce the cost of production and comply with recycling notion nowadays, but also enhance efficiency in the practical application of radioisotopes.
