| Abstract | ||
| Zirconium selenomolybdate99Mo gel was prepared by adsorption of 99Mo onto inactive zirconium selenomolybdate gel matrix. The batch equilibration method was used for investigation of the interaction between 99Mo (VI) radionuclide and the zirconium selenomolybdate gel matrix in HCl acid solutions. The apparent capacity of zirconium selenomolybdate for 99Mo(VI) was determined by dynamic method and was found to be 0.13 mmol/g. 99Mo/99mTc radioisotope generators of the elution mode was prepared based on adsorption of 99Mo radiotracer, of low specific activity, onto chromatographic columns packed with 2g zirconium selenomolybdate gel matrix. The radioactivity of 99mTc was eluted with 0.9% NaCl solution each 24 h at a flow rate 0.5 ml/min. The eluted 99mTc radioactivity was of high yield and quality over the period of investigation | ||
