Preparation of 95mTc radiotracer

摘要

Several procedures for preparation of the ~(95m)Tc radiotracer following irradiation of a thin Mo target with deuterons were tested. The procedures consisting of alkaline-oxidative fusion of the irradiated target in a mixture of Na_2O_2 + NaOH and subsequent liquid-liquid extraction with 2-butanone, and acid decomposition of the target in a mixture of H_2SO_4 + HNO_3 followed by extraction chromatography with PAN-Aliquat 336 composite material appeared suitable for the given purpose.
