Cette mthode repose sur le fait que l chantillon a incorpor de l uranium pendant sa formation et a un apport limit de thorium provenant de sources externes système ferm ce qui fait que tout le thorium dans la structure est le produit de la dsintgration U Th Tous les environnements de dpôt ne peuvent pas remplir ces
·In this study at first the TiO 2 nanoparticles surface was modified by SH functional group of 3 mercaptopropyltrimethoxysilane TMPTMS Then the novel mesoporous PVA/TiO 2 /TMPTMS composite nanofibers were synthesized via electrospinning method The aim of this study was the sorption of uranium and thorium on polyvinyl alcohol PVA /TiO 2
·Le thorium se prsente sous la forme d un seul isotope le thorium 232 Le noyau atomique du thorium possède 90 protons et 142 neutrons Le thorium se situe en fin du tableau de Mendeleïev Z = 90 dans la famille des actinides tout comme l uranium naturel Z = 92 1 Usages et intrêts Le thorium a t identifi vers 1830 en
·Le thorium 232 est par ailleurs le terme de plus longue demi vie de la chaîne de dsintgration du plutonium 244 une radioactivit teinte Le thorium se trouve en petites quantits dans la plupart des roches et sols il est quatre fois plus abondant que l uranium à peu près aussi frquent que le plomb
·Le thorium possède de nombreuses qualits mais galement de nombreux inconvnients difficile à manipuler mtal fertile et non fissile risques plus levs Mais il produit moins de dchets que le plutonium ou l uranium et reste une option attrayante pour l avenir de l nergie nuclaire
Nowadays titanium is manufactured by the Kroll process First you heat titanium dioxide with carbon to about 1000 degrees C and pass chlorine over it This makes TiCl4 People call that "Tickle" Then you cover the Tickle with an argon blanket and react with hot magnesium [at 850 degrees C] to get the metallic element

·The abundance of the actinides on Earth has been the topic of several studies Most of the research today concerns the abundance of uranium in the lithosphere and is based on the analysis of minerals rocks and ores Grenthe et al 2006 Thorium abundance has been investigated using models or experimental techniques and it has been found at relatively low
·The leaching behaviour n iobium tantalum thorium uranium titanium and rare earth eleme nts has been investigated on tantalite minerals c ollected from Kab Amiri using H 2 SO 4 at different
·The pioneering research & development in the nuclear domain was performed with the purpose of creating nuclear weapons Since the fission of thorium doesn t produce plutonium one of the elements used in nuclear weapons as a byproduct uranium the dual purpose nuclear fuel took precedence However nations have finally understood the safety
·In 1960 Welt and Smutz used tributylamine TBA and di n octylamine DOA solvents for the recovery of uranium and thorium from Egyptian monazite sulfate leach liquor Gupta et al in 2002 reported the use of Cyanex 923 for uranium thorium and lanthanides Ce Y from the digested leach solution of monazite in HNO 3 with HF and HClO 4
·L uranium est soluble dans l uranium 238 l isotope majoritaire se dsintègre lentement avec une demi vie de 4 47 milliards d annes pour se transformer par quelques tapes rapides en uranium 234 de demi vie 245 500 ans lequel se dsintègre ensuite par dsintgration α en thorium 230 de demi vie 75 000 ans Contrairement à l uranium le
