Abstract | ||||
ABSTRACT The reaction of 99mTc of different oxidation states (+7, +4) with 2-thiouracil and 5- nitrobarbituric acid have been studied at different temperatures, pH and concentrations. The reaction mixtures have been analyzed at different times using TLC and a radiodetctor to show the peaks at the plates.99mTc is obtained from the Mo generators with oxidation state (+7). The use of SnCl2 as a reducing agent gave 99mTc with oxidation state (+4). It is very difficult to separate the complexes formed from the reactions in very small concentration. The percentage of 99mTc and its oxidation state involved the complexes can be determined. | ||||
