Abstract
- Tracer technology plays an important role in industry development and has been widely used to optimize process, solve problems and improve product quality. In the last years Cuban scientifics have studied the 99mTcO4 -, eluted from 99Mo/99mTc generator, extraction with the mixture 30 % tributylphosphate -16 % trioctilamine in cyclohexane, in order to get an organic radiotracer. In this paper, the influence on 99mTcO4 - extraction of stirring speed, contact time and NaCl concentration were studied. The extractant's role was also studied and, the tracer´s homogeneity in diesel, special gasoline and Venezuelan oils was evaluated to normal pressure and temperature. The obtained outcomes showed that the NaCl concentration only influences on the extraction process when it is less than 0.17 %. Furthermore, the employed mixture´s synergism was noticed and, could be conclude that, the obtained tracer is a physical radiotracer for the used industrial supports to 95 % trustworthy.
