A method for purifying Ac from a mixture includes Ac and at least one element selected from Ra, Pb, Po, Bi and La. The method includes the steps of: (a) performing a first separation using a first extraction chromatographic column based on a first resin (either a diglycolamide resin or a dialkylphosphoric acid resin) and a first matrix solution; and (b) performing a second separation using a second extraction chromatographic column based on a second resin (respectively either a dialkylphosphoric acid resin or a diglycolamide resin).

Purification of actinium

A method for producing Pb-212 and Ac-225 isotopes includes irradiating a Ra-226 containing target with charged particles and producing an irradiated target having at least Ac-225 isotope particles. Following irradiation and a cooling period, actinium isotopes are separated from a residual radium-containing fraction using chromatography. Subsequently, after an additional waiting period, lead isotopes are separated from the remaining radium fraction through extraction chromatography. The extraction process employs a resin containing an 18-crown-6 ether or an equivalent in a nitric acid (HNO3) and/or hydrochloric acid (HCl) medium to isolate Pb-212 and Ac-225 isotope particles.
