Abstract
Process for the purification and concentration of isotopes which isotopes are dissolved in a dilute acidic solution and adsorbed on an (optionally) activated surface of a d10-metal whereby the isotopes are selectively desorbed by elution whereby in situ reduction of oxidation products is achieved and an apparatus for performing said process.
Claims21
Process for the purification of radioisotopes wherein the isotopes are dissolved in a dilute acidic solution and adsorbed on the surface of a metal selected from the group consisting of platinum, palladium and nickel whereby the isotopes are selectively desorbed by elution with an eluent in the presence of hydrogen gas.
Process for the concentration of radioisotopes wherein the isotopes are dissolved in a dilute acidic solution and adsorbed on the surface of a metal selected from the group consisting of platinum, palladium and nickel whereby the isotopes are selectively desorbed by elution with an eluent in the presence of hydrogen gas.
Process for the purification and concentration of radioisotopes wherein the isotopes are dissolved in a dilute acidic solution and adsorbed on the surface of a metal selected from the group consisting of platinum, palladium and nickel whereby the isotopes are selectively desorbed by elution with an eluent in the presence of hydrogen gas.
Process for preparing a transportable form of a radioiodine isotope whereby the isotope is absorbed on a metal selected from the group consisting of platinum, palladium and nickel.
Process for the purification and concentration of radioiodine isotopes comprising the steps of:
- a. providing a platinum surface in a column;
- b. loading the column with an acidic radioiodine solution, and;
- c. eluting the column, providing that prior to step a there is a step of activating the platinum surface with hydrogen gas.
