Abstract
The present invention provides a method for fabricating an indium(In)-111 radioactive isotope. A target of cadmium(Cd)-112 is processed through steps of dissolving with heat, absorbing, washing, desorbing and drying for obtaining the In-111 radioactive isotope. Thus, chemical separation is coordinated with the target for fabricating the In-111 radioactive isotope with high efficiency and low cost for production procedure.
Claims12
A method of fabricating an indium(In)-111 radioactive isotope, comprising steps of:
- (a) obtaining a heating plate in a bromic acid solution with a target having a surface of cadmium(Cd)-112 obtained on said heating plate and adding pressure on said target to be dissolved with heat coordinated with said heating plate to obtain a solution of In-111 and Cd-112;
- (b) extracting said solution of In-111 and Cd-112 to be put into a tube to process ion exchange to adsorb In-111 in said tube and drain a solution of Cd-112;
- (c) adding a bromic acid solution into said tube to wash out In-111 with a waste liquid drained;
- (d) adding a bromic acid solution into said tube to desorb In-111 with said bromic acid solution drained together to obtain an In-111 semi-product liquid;
- and
- (e) drying said In-111 semi-product liquid to obtain a product of In-111 radioactive isotope.
