Resumen

The Nuclear Metrology Laboratory (LMN) at IPEN-CNEN/SP is developing a research project aimed at studying analytical techniques for determining radioactive impurities, emitting alpha and beta particles. This project started with the determination of impurities present in ⁹⁹Mo, which is used to obtain the radiopharmaceutical ^99mTc by means of radiochemical separation in the ⁹⁹Mo/^99mTc generator. The study of the anionic extracting agent Strata X-A widely used in quality analysis, was realized by means a breakthrough curve in order to validate its total exchange capacity for Mo. The breaking point was determined at (2.75 +/- 0.14) mL, showing that just one 0.5 g Strata X-A cartridge is sufficient to retain 1.0 mL of a (Na₂MoO₄+ ⁹⁹Mo) solution in concentration of 2.42 g L^- 1.
