Production of 93mMo through natY(7Li, 3n) reaction and subsequent studies on separation and extraction behaviour of no-carrier-added 93mMo from an yttrium target.
The present work reports heavy-ion-assisted production of (93m)Mo from a natural yttrium target using the (89)Y((7)Li, 3n)(93m)Mo reaction. Three different methodologies based on liquid-liquid extraction (LLX), aqueous biphasic extraction and precipitation, have been developed for separation and extraction of no-carrier-added (nca) (93m)Mo (T(1/2)=6.85h) radionuclide from bulk yttrium target. Complete separation of nca Mo from the target Y has been achieved by employing LLX technique with 0.1M trioctylamine (TOA) dissolved in cyclohexane and 8M HCl. Quantitative separation of (93m)Mo from the yttrium target is also possible by precipitating bulk yttrium with 1M oxalic acid. However, for this particular case, studies have shown that the aqueous biphasic extraction is not the method of choice for separation of nca Mo. Nevertheless, the extraction pattern is important in the context of simulation experiments for studying the behaviour of (106)Sg. Similarity or dissimilarity between the extraction patterns in various analytical systems will be helpful to decisively place Sg in the right position in the periodic table.
