The ion-exchange behavior of 68Ga in mixed HCl–ethanol media on cation and anion exchangers was studied. The mass distribution coefficients of 68Ga on Dowex 50?W?×?8 and Dowex 1?×?8 ion-exchange resins at HCl concentrations in the range 0.1-.0?M and with ethanol volume fractions 0-0?% were determined. The dynamic characteristics of the 68Ga ion exchange in mixed HCl–ethanol solutions were studied. A process, based on the data obtained, was developed for preparing of 68Ga solutions in 0.1?M HCl with high chemical and radiochemical purity that are suitable for producing of 68Ga-radiopharmaceuticals with required quality for clinical use. The suitability of the process for the synthesis of different 68Ga-radiopharmaceuticals in routine clinical practice was demonstrated.
