Uranium nitrogen activation

Murthy and Ryan [823] used colloid flotation as a means of preconcentration prior to neutron activation analysis for arsenic, molybdenum, uranium, and vanadium. Hydrous iron (III) oxide is floated in the presence of sodium decyl sulfate with small nitrogen bubbles from 1 litre of seawater at pH 5.7. Recoveries of arsenic, molybdenum, and vanadium were better than 95%, whilst that of uranium was about 75%. [Pg.282]

E. Kayser and H. Delaval observed that the presence of a radioactive uranium mineral increased the activity of nitrogen-fixing bacteria. A. W. Bosworth and co-workers observed that ammonia is produced by the human tubercle bacillus. [Pg.360]
