- Abstract
The cross-linked chitosan polymer (CCM) is an emerging adsorbent matrix. The CCM matrix has very high adsorption for Mo and thus can be utilized to prepare Mo/Tc generator using low-specific activity (n, γ) Mo. The elution efficiency of Tc from Mo/Tc generator based on the CCM polymer oxidized and non-oxidized form has been found more than 75% and about 40%, respectively. The Na[Tc]TcO eluates obtained were clear solutions with pH 5-6 and the R C Purities of 99%. The Mo breakthrough in the Tc fraction with alumina guard column (0.5 g) was 0.002 ± 0.003 ( n = 9). The radionuclidic purity of TcO was more than 99.99%. The Al and Mo content in the eluted Tc was less than 10 µg/ml. The R C Purity of the labeled compounds was greater than 95%.
