Final answer:
The eluate cannot be used for reconstituting kits for patient injection due to the presence of Al3+ ions.
Step-by-step explanation:
Technetium-99m (Tc-99m) is a radioisotope commonly used in medical procedures due to its short half-life and low radiation dose. The Tc-99m is generated from parent nuclide Mo-99, which undergoes β decay with a longer half-life of 66 hours. In the process, the molybdate ion MoO42- is converted to the pertechnetate ion TcO4-. These two ions can be separated using column chromatography.
In this case, the eluate contains 30 µg of Al3+. Since the eluate is intended for reconstituting kits for patient injection, the presence of Al3+ can interfere with the desired medical procedures. Therefore, it is recommended not to use this eluate for reconstituting the kits. The eluate should be discarded or thoroughly purified to remove the unwanted Al3+ ions.
