摘要

In sedimentary apatite two types of uranyl were observed, sorption of uranyl aquecomplexes and films of uranyl minerals. Tetravalent uranium is detected by the weak reabsorption lines. Hexavalent uranium was detected after oxidizing thermal treatment at 1100 K, as concentrated in fluorite phase which is formed as result of heating. Uranyl luminescence is absent in magmatic apatites before and after oxidizing heating, indicating that the main form is due to tetravalent uranium. (C) 1998 Elsevier Science S.A. [References: 15]
