Abstract
A radioisotope TI-201 is produced. The process includes electroplating, irradiating, dissolving, precipitating, ion exchanging, decaying and filtering. The TI-201 obtained is a liquid having a high purity.
Claims4
A radioisotope TI-201 production process, comprising steps of:
- (a) Electroplating:
- wherein a TI-203 solid target material is obtained from a plated target material of TI-203 through electroplating;
- (b) Irradiating:
- wherein said TI-203 solid target material is irradiated with a proton beam by using a cyclotron;
- (c) Processing a first chemical separation:
- wherein said TI-203 solid target material is dissolved with a strong acid liquid to be separated into a TI-201 liquid and a Pb-201 liquid with impurities filtered out;
- (d) Decaying:
- wherein said Pb-201 liquid is obtained to be decayed into a TI-201 liquid;
- and
- (e) Processing a second chemical separation:
- wherein a TI-201 liquid having a high purity is obtained through filtering,
- wherein said step (c) comprises steps of:
- (c1) Dissolving:
- wherein, after said irradiating, said TI-203 solid target material is dissolved with a strong acid liquid to obtain a Pb-201 solution and a TI-203 solution;
- (c2) Processing a precipitation:
- wherein ammonia (NH3) and water are applied to said Pb-201 solution and said TI-203 solution for a precipitation to obtain a TI-201 liquid and a Pb-201 liquid;
- and
- (c3) Processing a first ion exchange:
- wherein hydrochloric acid (HCl) is applied to said TI-201 liquid and said Pb-201 liquid for an ion exchange by using a resin with impurities filtered out,
- wherein said strong acid liquid used in step (c1) is a solution of nitric acid having ferric iron (HNO3/Fe3/H2O),
- wherein step (e) is a second ion exchange;
- and
- wherein an HCl having sulfur dioxide (SO2) is applied to said TI-201 liquid to obtain a TI-201 liquid having a high purity through a second ion exchange by using a resin.
