Treatment and labeling of silica sand for obtaining a prospective solid 99mTc radiotracer

Abstract Pretreated silica sand labeling using varying concentrations of tin(II) fluoride and chloride as reducing agents different times was performed in order to develop a methodology for with 99m Tc solid radiotracer. Influence pretreatment parameters on the sorption yield (R ret% ) statistically evaluated. The effectiveness methods used reduce pertechnetate ( TcO 4 − by ascending paper chromatography confirmed. Results show relatively high values yields sand. It possible establish obtaining labeled radiotracers support
