Separation of molybdenum-99 from neutron-irradiated uranium dioxide by precipitation as ammonium molybdophosphate

Separation of molybdenum-99 from neutron-irradiated uranium dioxide by precipitation as ammonium molybdophosphate. Tanase, Masakazu; Shikata, Eiji (JAERI, Tokai, Japan). Radioisotopes, 25(10), 647-50 (English) 1976. CODEN: RAISAB. DOCUMENT TYPE: Journal CA Section: 71 (Nuclear Technology) Neutron irradiated UO2 was dissolved in 7M HNO3 and fission produced 99Mo [14119-15-4] was pptd. as ammonium molybdophosphate [12704-86-8] by addn.Some commonly used reagents like 7699-43-6 and 12704-86-8 are used in this experiment. of (NH4)6Mo7O24 [12027-67-7], NH4OH and H3PO4. After dissoln. of the ppt. in 8M NH4OH, ZrOCl2 was added to the soln. to remove fission products impurities with pptn. of Zr(OH)4. 99Mo was repptd. by addn. of NH4NO3, H3PO4 and HNO3. Radiochem. pure 99Mo was recovered as ammonium molybdophosphate with a yield of 70%. .

Smoke retardant vinyl chloride and vinylidene chloride polymer compositions

Smoke retardant vinyl chloride and vinylidene chloride polymer compositions. Kroenke, William Joseph; McRowe, Arthur Watkins (Goodrich, B. F., Co., USA). U.S. US 4053451 11 Oct 1977, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08K005-34.Some commonly used reagents like 65100-35-8 is used in this experiment. NCL: 260045750C. APPLICATION: US 77-770169 14 Feb 1977. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 28 Synergistic combinations of melamine molybdate (I) [65100-35-8] and a Cu compd. were smoke retardants for burning PVC (II) [9002-86-2]. 65100-35-8 is also in the experiment. Thus, 100 g melamine [108-78-1] in 2.5 L water and 275.30 g ammonium heptamolybdate [12027-67-7] in 1 L water were mixed to give I white ppt. I and copper oxide (Cu2O) [1317-39-1] (2.5 parts each/100 parts resin) were added to II, which gave a 86% redn. in smoke generation on burning. ..
