The separation of <SUP>99</SUP>Mo from other fission products has been successfully attempted by isolating S in a HNO<SUB>3</SUB> solution of neutron-irradiated UO<SUB>2</SUB> and collecting <SUP>99</SUP>Mo on it. Influence of various factors on the separation of <SUP>99</SUP>Mo was examined. When 5% aqueous solution of K<SUB>2</SUB>S was added to the solution of fission products of high HNO<SUB>3</SUB> concentration and the mixture of S stood for 10 min, over 80% of the <SUP>99</SUP>Mo could be separated with the precipitate. Besides <SUP>99</SUP>Mo, <SUP>132</SUP>Te, <SUP>103</SUP>Ru and other nuclides also accompanied the precipitate. The presence of Mo carrier and U affected greatly the separation of <SUP>99</SUP>Mo, but that of Zr or Te carrier did not.
